+Git 1.8.1.1 Release Notes
+=========================
+
+Fixes since v1.8.1
+------------------
+
+ * The attribute mechanism didn't allow limiting attributes to be
+   applied to only a single directory itself with "path/" like the
+   exclude mechanism does.
+
+ * When attempting to read the XDG-style $HOME/.config/git/config and
+   finding that $HOME/.config/git is a file, we gave a wrong error
+   message, instead of treating the case as "a custom config file does
+   not exist there" and moving on.
+
+ * After failing to create a temporary file using mkstemp(), failing
+   pathname was not reported correctly on some platforms.
+
+ * http transport was wrong to ask for the username when the
+   authentication is done by certificate identity.
+
+ * The behaviour visible to the end users was confusing, when they
+   attempt to kill a process spawned in the editor that was in turn
+   launched by Git with SIGINT (or SIGQUIT), as Git would catch that
+   signal and die.  We ignore these signals now.
+
+ * A child process that was killed by a signal (e.g. SIGINT) was
+   reported in an inconsistent way depending on how the process was
+   spawned by us, with or without a shell in between.
+
+ * After "git add -N" and then writing a tree object out of the
+   index, the cache-tree data structure got corrupted.
+
+ * "git apply" misbehaved when fixing whitespace breakages by removing
+   excess trailing blank lines in some corner cases.
+
+ * A tar archive created by "git archive" recorded a directory in a
+   way that made NetBSD's implementation of "tar" sometimes unhappy.
+
+ * When "git clone --separate-git-dir=$over_there" is interrupted, it
+   failed to remove the real location of the $GIT_DIR it created.
+   This was most visible when interrupting a submodule update.
+
+ * "git fetch --mirror" and fetch that uses other forms of refspec
+   with wildcard used to attempt to update a symbolic ref that match
+   the wildcard on the receiving end, which made little sense (the
+   real ref that is pointed at by the symbolic ref would be updated
+   anyway).  Symbolic refs no longer are affected by such a fetch.
+
+ * The "log --graph" codepath fell into infinite loop in some
+   corner cases.
+
+ * "git merge" started calling prepare-commit-msg hook like "git
+   commit" does some time ago, but forgot to pay attention to the exit
+   status of the hook.
+
+ * "git pack-refs" that ran in parallel to another process that
+   created new refs had a race that can lose new ones.
+
+ * When a line to be wrapped has a solid run of non space characters
+   whose length exactly is the wrap width, "git shortlog -w" failed
+   to add a newline after such a line.
+
+ * The way "git svn" asked for password using SSH_ASKPASS and
+   GIT_ASKPASS was not in line with the rest of the system.
+
+ * "gitweb", when sorting by age to show repositories with new
+   activities first, used to sort repositories with absolutely
+   nothing in it early, which was not very useful.

+   "config.status --recheck" even when unnecessary.
+
+ * Some scripted programs written in Python did not get updated when
+   PYTHON_PATH changed.
+
+ * We have been carrying a translated and long-unmaintained copy of an
+   old version of the tutorial; removed.
+
+ * Portability issues in many self-test scripts have been addressed.

+
+ * An element on GIT_CEILING_DIRECTORIES list that does not name the

+   the GIT_DIR discovery logic to escape the ceiling.
+
+ * Command line completion for "tcsh" emitted an unwanted space
+   after completing a single directory name.
+
+ * Command line completion leaked an unnecessary error message while
+   looking for possible matches with paths in <tree-ish>.
+
+ * "git archive" did not record uncompressed size in the header when
+   streaming a zip archive, which confused some implementations of unzip.
+
+ * When users spelled "cc:" in lowercase in the fake "header" in the
+   trailer part, "git send-email" failed to pick up the addresses from
+   there. As e-mail headers field names are case insensitive, this
+   script should follow suit and treat "cc:" and "Cc:" the same way.

+Fixes since v1.8.1.2
+--------------------
+
+ * The attribute mechanism didn't allow limiting attributes to be
+   applied to only a single directory itself with "path/" like the
+   exclude mechanism does.  The fix for this in 1.8.1.2 had
+   performance degradations.
+
+ * Command line completion code was inadvertently made incompatible with
+   older versions of bash by using a newer array notation.
+
+ * Scripts to test bash completion was inherently flaky as it was
+   affected by whatever random things the user may have on $PATH.
+
+ * A fix was added to the build procedure to work around buggy
+   versions of ccache broke the auto-generation of dependencies, which
+   unfortunately is still relevant because some people use ancient
+   distros.
+
+ * We used to stuff "user@" and then append what we read from
+   /etc/mailname to come up with a default e-mail ident, but a bug
+   lost the "user@" part.
+
+ * "git am" did not parse datestamp correctly from Hg generated patch,
+   when it is run in a locale outside C (or en).
+
+ * Attempt to "branch --edit-description" an existing branch, while
+   being on a detached HEAD, errored out.
+
+ * "git cherry-pick" did not replay a root commit to an unborn branch.
+
+ * We forgot to close the file descriptor reading from "gpg" output,
+   killing "git log --show-signature" on a long history.
+
+ * "git rebase --preserve-merges" lost empty merges in recent versions
+   of Git.
+
+ * Rebasing the history of superproject with change in the submodule
+   has been broken since v1.7.12.
+
+ * A failure to push due to non-ff while on an unborn branch
+   dereferenced a NULL pointer when showing an error message.

+Also contains various documentation fixes.

+   which may confuse users to expect a "negative match", which does
+   not exist.  This has been demoted to a warning; such an entry is
+   still ignored.
+
+ * "git apply --summary" has been taught to make sure the similarity
+   value shown in its output is sensible, even when the input had a
+   bogus value.
+
+ * "git clean" showed what it was going to do, but sometimes ended
+   up finding that it was not allowed to do so, which resulted in a
+   confusing output (e.g. after saying that it will remove an
+   untracked directory, it found an embedded git repository there
+   which it is not allowed to remove).  It now performs the actions
+   and then reports the outcome more faithfully.
+
+ * "git clone" used to allow --bare and --separate-git-dir=$there
+   options at the same time, which was nonsensical.
+
+ * "git cvsimport" mishandled timestamps at DST boundary.
+
+ * We used to have an arbitrary 32 limit for combined diff input,
+   resulting in incorrect number of leading colons shown when showing
+   the "--raw --cc" output.
+
+ * The smart HTTP clients forgot to verify the content-type that comes
+   back from the server side to make sure that the request is being
+   handled properly.
+
+ * "git help remote-helpers" failed to find the documentation.
+
+ * "gitweb" pages served over HTTPS, when configured to show picon or
+   gravatar, referred to these external resources to be fetched via
+   HTTP, resulting in mixed contents warning in browsers.
+
+Also contains various documentation fixes.

+Git 1.8.1.6 Release Notes
+=========================
+
+Fixes since v1.8.1.5
+--------------------
+
+ * An earlier change to the attribute system introduced at v1.8.1.2 by
+   mistake stopped a pattern "dir" (without trailing slash) from
+   matching a directory "dir" (it only wanted to allow pattern "dir/"
+   to also match).
+
+ * The code to keep track of what directory names are known to Git on
+   platforms with case insensitive filesystems can get confused upon a
+   hash collision between these pathnames and looped forever.
+
+ * When the "--prefix" option is used to "checkout-index", the code
+   did not pick the correct output filter based on the attribute
+   setting.
+
+ * Annotated tags outside refs/tags/ hierarchy were not advertised
+   correctly to the ls-remote and fetch with recent version of Git.
+
+ * The logic used by "git diff -M --stat" to shorten the names of
+   files before and after a rename did not work correctly when the
+   common prefix and suffix between the two filenames overlapped.
+
+ * "git update-index -h" did not do the usual "-h(elp)" thing.
+
+ * perl/Git.pm::cat_blob slurped everything in core only to write it
+   out to a file descriptor, which was not a very smart thing to do.
+
+ * The SSL peer verification done by "git imap-send" did not ask for
+   Server Name Indication (RFC 4366), failing to connect SSL/TLS
+   sites that serve multiple hostnames on a single IP.
+
+ * "git bundle verify" did not say "records a complete history" for a
+   bundle that does not have any prerequisites.
+
+Also contains various documentation fixes.

+Git v1.8.1 Release Notes
+========================
+
+Backward compatibility notes
+----------------------------
+
+In the next major release (not *this* one), we will change the
+behavior of the "git push" command.
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  We will use the "simple" semantics that pushes the
+current branch to the branch with the same name, only when the current
+branch is set to integrate with that remote branch.  There is a user
+preference configuration variable "push.default" to change this, and
+"git push" will warn about the upcoming change until you set this
+variable in this release.
+
+"git branch --set-upstream" is deprecated and may be removed in a
+relatively distant future.  "git branch [-u|--set-upstream-to]" has
+been introduced with a saner order of arguments to replace it.
+
+
+Updates since v1.8.0
+--------------------
+
+UI, Workflows & Features
+
+ * Command-line completion scripts for tcsh and zsh have been added.
+
+ * "git-prompt" scriptlet (in contrib/completion) can be told to paint
+   pieces of the hints in the prompt string in colors.
+
+ * Some documentation pages that used to ship only in the plain text
+   format are now formatted in HTML as well.
+
+ * We used to have a workaround for a bug in ancient "less" that
+   causes it to exit without any output when the terminal is resized.
+   The bug has been fixed in "less" version 406 (June 2007), and the
+   workaround has been removed in this release.
+
+ * When "git checkout" checks out a branch, it tells the user how far
+   behind (or ahead) the new branch is relative to the remote tracking
+   branch it builds upon.  The message now also advises how to sync
+   them up by pushing or pulling.  This can be disabled with the
+   advice.statusHints configuration variable.
+
+ * "git config --get" used to diagnose presence of multiple
+   definitions of the same variable in the same configuration file as
+   an error, but it now applies the "last one wins" rule used by the
+   internal configuration logic.  Strictly speaking, this may be an
+   API regression but it is expected that nobody will notice it in
+   practice.
+
+ * A new configuration variable "diff.context" can be used to
+   give the default number of context lines in the patch output, to
+   override the hardcoded default of 3 lines.
+
+ * "git format-patch" learned the "--notes=<ref>" option to give
+   notes for the commit after the three-dash lines in its output.
+
+ * "git log -p -S<string>" now looks for the <string> after applying
+   the textconv filter (if defined); earlier it inspected the contents
+   of the blobs without filtering.
+
+ * "git log --grep=<pcre>" learned to honor the "grep.patterntype"
+   configuration set to "perl".
+
+ * "git replace -d <object>" now interprets <object> as an extended
+   SHA-1 (e.g. HEAD~4 is allowed), instead of only accepting full hex
+   object name.
+
+ * "git rm $submodule" used to punt on removing a submodule working
+   tree to avoid losing the repository embedded in it.  Because
+   recent git uses a mechanism to separate the submodule repository
+   from the submodule working tree, "git rm" learned to detect this
+   case and removes the submodule working tree when it is safe to do so.
+
+ * "git send-email" used to prompt for the sender address, even when
+   the committer identity is well specified (e.g. via user.name and
+   user.email configuration variables).  The command no longer gives
+   this prompt when not necessary.
+
+ * "git send-email" did not allow non-address garbage strings to
+   appear after addresses on Cc: lines in the patch files (and when
+   told to pick them up to find more recipients), e.g.
+
+     Cc: Stable Kernel <stable@k.org> # for v3.2 and up
+
+   The command now strips " # for v3.2 and up" part before adding the
+   remainder of this line to the list of recipients.
+
+ * "git submodule add" learned to add a new submodule at the same
+   path as the path where an unrelated submodule was bound to in an
+   existing revision via the "--name" option.
+
+ * "git submodule sync" learned the "--recursive" option.
+
+ * "diff.submodule" configuration variable can be used to give custom
+   default value to the "git diff --submodule" option.
+
+ * "git symbolic-ref" learned the "-d $symref" option to delete the
+   named symbolic ref, which is more intuitive way to spell it than
+   "update-ref -d --no-deref $symref".
+
+
+Foreign Interface
+
+ * "git cvsimport" can be told to record timezones (other than GMT)
+   per-author via its author info file.
+
+ * The remote helper interface to interact with subversion
+   repositories (one of the GSoC 2012 projects) has been merged.
+
+ * A new remote-helper interface for Mercurial has been added to
+   contrib/remote-helpers.
+
+ * The documentation for git(1) was pointing at a page at an external
+   site for the list of authors that no longer existed.  The link has
+   been updated to point at an alternative site.
+
+
+Performance, Internal Implementation, etc.
+
+ * Compilation on Cygwin with newer header files are supported now.
+
+ * A couple of low-level implementation updates on MinGW.
+
+ * The logic to generate the initial advertisement from "upload-pack"
+   (i.e. what is invoked by "git fetch" on the other side of the
+   connection) to list what refs are available in the repository has
+   been optimized.
+
+ * The logic to find set of attributes that match a given path has
+   been optimized.
+
+ * Use preloadindex in "git diff-index" and "git update-index", which
+   has a nice speedup on systems with slow stat calls (and even on
+   Linux).
+
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.8.0
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.0 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * The configuration parser had an unnecessary hardcoded limit on
+   variable names that was not checked consistently.
+
+ * The "say" function in the test scaffolding incorrectly allowed
+   "echo" to interpret "\a" as if it were a C-string asking for a
+   BEL output.
+
+ * "git mergetool" feeds /dev/null as a common ancestor when dealing
+   with an add/add conflict, but p4merge backend cannot handle
+   it. Work it around by passing a temporary empty file.
+
+ * "git log -F -E --grep='<ere>'" failed to use the given <ere>
+   pattern as extended regular expression, and instead looked for the
+   string literally.
+
+ * "git grep -e pattern <tree>" asked the attribute system to read
+   "<tree>:.gitattributes" file in the working tree, which was
+   nonsense.
+
+ * A symbolic ref refs/heads/SYM was not correctly removed with "git
+   branch -d SYM"; the command removed the ref pointed by SYM
+   instead.
+
+ * Update "remote tracking branch" in the documentation to
+   "remote-tracking branch".
+
+ * "git pull --rebase" run while the HEAD is detached tried to find
+   the upstream branch of the detached HEAD (which by definition
+   does not exist) and emitted unnecessary error messages.
+
+ * The refs/replace hierarchy was not mentioned in the
+   repository-layout docs.
+
+ * Various rfc2047 quoting issues around a non-ASCII name on the
+   From: line in the output from format-patch have been corrected.
+
+ * Sometimes curl_multi_timeout() function suggested a wrong timeout
+   value when there is no file descriptor to wait on and the http
+   transport ended up sleeping for minutes in select(2) system call.
+   A workaround has been added for this.
+
+ * For a fetch refspec (or the result of applying wildcard on one),
+   we always want the RHS to map to something inside "refs/"
+   hierarchy, but the logic to check it was not exactly right.
+   (merge 5c08c1f jc/maint-fetch-tighten-refname-check later to maint).
+
+ * "git diff -G<pattern>" did not honor textconv filter when looking
+   for changes.
+
+ * Some HTTP servers ask for auth only during the actual packing phase
+   (not in ls-remote phase); this is not really a recommended
+   configuration, but the clients used to fail to authenticate with
+   such servers.
+   (merge 2e736fd jk/maint-http-half-auth-fetch later to maint).
+
+ * "git p4" used to try expanding malformed "$keyword$" that spans
+   across multiple lines.
+
+ * Syntax highlighting in "gitweb" was not quite working.
+
+ * RSS feed from "gitweb" had a xss hole in its title output.
+
+ * "git config --path $key" segfaulted on "[section] key" (a boolean
+   "true" spelled without "=", not "[section] key = true").
+
+ * "git checkout -b foo" while on an unborn branch did not say
+   "Switched to a new branch 'foo'" like other cases.
+
+ * Various codepaths have workaround for a common misconfiguration to
+   spell "UTF-8" as "utf8", but it was not used uniformly.  Most
+   notably, mailinfo (which is used by "git am") lacked this support.
+
+ * We failed to mention a file without any content change but whose
+   permission bit was modified, or (worse yet) a new file without any
+   content in the "git diff --stat" output.
+
+ * When "--stat-count" hides a diffstat for binary contents, the total
+   number of added and removed lines at the bottom was computed
+   incorrectly.
+
+ * When "--stat-count" hides a diffstat for unmerged paths, the total
+   number of affected files at the bottom of the "diff --stat" output
+   was computed incorrectly.
+
+ * "diff --shortstat" miscounted the total number of affected files
+   when there were unmerged paths.
+
+ * "update-ref -d --deref SYM" to delete a ref through a symbolic ref
+   that points to it did not remove it correctly.

+Git v1.8.2.1 Release Notes
+==========================
+
+Fixes since v1.8.2
+------------------
+
+ * An earlier change to the attribute system introduced at v1.8.1.2 by
+   mistake stopped a pattern "dir" (without trailing slash) from
+   matching a directory "dir" (it only wanted to allow pattern "dir/"
+   to also match).
+
+ * Verification of signed tags were not done correctly when not in C
+   or en/US locale.
+
+ * 'git commit -m "$msg"' used to add an extra newline even when
+   $msg already ended with one.
+
+ * The "--match=<pattern>" option of "git describe", when used with
+   "--all" to allow refs that are not annotated tags to be used as a
+   base of description, did not restrict the output from the command
+   to those that match the given pattern.
+
+ * An aliased command spawned from a bare repository that does not say
+   it is bare with "core.bare = yes" is treated as non-bare by mistake.
+
+ * When "format-patch" quoted a non-ascii strings on the header files,
+   it incorrectly applied rfc2047 and chopped a single character in
+   the middle of it.
+
+ * "git archive" reports a failure when asked to create an archive out
+   of an empty tree.  It would be more intuitive to give an empty
+   archive back in such a case.
+
+ * "git tag -f <tag>" always said "Updated tag '<tag>'" even when
+   creating a new tag (i.e. not overwriting nor updating).
+
+ * "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and
+   instead the parser kept reading beyond the end of the string.
+
+ * Annotated tags outside refs/tags/ hierarchy were not advertised
+   correctly to the ls-remote and fetch with recent version of Git.
+
+ * The code to keep track of what directory names are known to Git on
+   platforms with case insensitive filesystems can get confused upon a
+   hash collision between these pathnames and looped forever.
+
+ * The logic used by "git diff -M --stat" to shorten the names of
+   files before and after a rename did not work correctly when the
+   common prefix and suffix between the two filenames overlapped.
+
+ * "git submodule update", when recursed into sub-submodules, did not
+   accumulate the prefix paths.
+
+ * "git am $maildir/" applied messages in an unexpected order; sort
+   filenames read from the maildir/ in a way that is more likely to
+   sort messages in the order the writing MUA meant to, by sorting
+   numeric segment in numeric order and non-numeric segment in
+   alphabetical order.
+
+ * When export-subst is used, "zip" output recorded incorrect
+   size of the file.
+
+ * Some platforms and users spell UTF-8 differently; retry with the
+   most official "UTF-8" when the system does not understand the
+   user-supplied encoding name that are the common alternative
+   spellings of UTF-8.
+
+ * "git branch" did not bother to check nonsense command line
+   parameters and issue errors in many cases.
+
+ * "git update-index -h" did not do the usual "-h(elp)" thing.
+
+ * perl/Git.pm::cat_blob slurped everything in core only to write it
+   out to a file descriptor, which was not a very smart thing to do.
+
+ * The SSL peer verification done by "git imap-send" did not ask for
+   Server Name Indication (RFC 4366), failing to connect SSL/TLS
+   sites that serve multiple hostnames on a single IP.
+
+ * "git index-pack" had a buffer-overflow while preparing an
+   informational message when the translated version of it was too
+   long.
+
+ * Clarify in the documentation "what" gets pushed to "where" when the
+   command line to "git push" does not say these explicitly.
+
+ * In "git reflog expire", REACHABLE bit was not cleared from the
+   correct objects.
+
+ * The "--color=<when>" argument to the commands in the diff family
+   was described poorly.
+
+ * The arguments given to pre-rebase hook were not documented.
+
+ * The v4 index format was not documented.
+
+ * The "--match=<pattern>" argument "git describe" takes uses glob
+   pattern but it wasn't obvious from the documentation.
+
+ * Some sources failed to compile on systems that lack NI_MAXHOST in
+   their system header (e.g. z/OS).
+
+ * Add an example use of "--env-filter" in "filter-branch"
+   documentation.
+
+ * "git bundle verify" did not say "records a complete history" for a
+   bundle that does not have any prerequisites.
+
+ * In the v1.8.0 era, we changed symbols that do not have to be global
+   to file scope static, but a few functions in graph.c were used by
+   CGit from sideways bypassing the entry points of the API the
+   in-tree users use.
+
+ * "git merge-tree" had a typo in the logic to detect d/f conflicts,
+   which caused it to segfault in some cases.

+Git v1.8.2.2 Release Notes
+==========================
+
+Fixes since v1.8.2.1
+--------------------
+
+ * Zsh completion forgot that '%' character used to signal untracked
+   files needs to be escaped with another '%'.
+
+ * A commit object whose author or committer ident are malformed
+   crashed some code that trusted that a name, an email and an
+   timestamp can always be found in it.
+
+ * The new core.commentchar configuration was not applied to a few
+   places.
+
+ * "git pull --rebase" did not pass "-v/-q" options to underlying
+   "git rebase".
+
+ * When receive-pack detects error in the pack header it received in
+   order to decide which of unpack-objects or index-pack to run, it
+   returned without closing the error stream, which led to a hang
+   sideband thread.
+
+ * "git diff --diff-algorithm=algo" was understood by the command line
+   parser, but "git diff --diff-algorithm algo" was not.
+
+ * "git log -S/-G" started paying attention to textconv filter, but
+   there was no way to disable this.  Make it honor --no-textconv
+   option.
+
+ * "git merge $(git rev-parse v1.8.2)" behaved quite differently from
+   "git merge v1.8.2", as if v1.8.2 were written as v1.8.2^0 and did
+   not pay much attention to the annotated tag payload.  Make the code
+   notice the type of the tag object, in addition to the dwim_ref()
+   based classification the current code uses (i.e. the name appears
+   in refs/tags/) to decide when to special case merging of tags.
+
+ * "git cherry-pick" and "git revert" can take more than one commit
+   on the command line these days, but it was not mentioned on the usage
+   text.
+
+ * Perl scripts like "git-svn" closed (not redirecting to /dev/null)
+   the standard error stream, which is not a very smart thing to do.
+   Later open may return file descriptor #2 for unrelated purpose, and
+   error reporting code may write into them.
+
+ * "git apply --whitespace=fix" was not prepared to see a line getting
+   longer after fixing whitespaces (e.g. tab-in-indent aka Python).
+
+ * "git diff/log --cc" did not work well with options that ignore
+   whitespace changes.
+
+ * Documentation on setting up a http server that requires
+   authentication only on the push but not fetch has been clarified.
+
+ * A few bugfixes to "git rerere" working on corner case merge
+   conflicts have been applied.
+
+ * "git bundle" did not like a bundle created using a commit without
+   any message as its one of the prerequisites.

+Git v1.8.2 Release Notes
+========================
+
+Backward compatibility notes (this release)
+-------------------------------------------
+
+"git push $there tag v1.2.3" used to allow replacing a tag v1.2.3
+that already exists in the repository $there, if the rewritten tag
+you are pushing points at a commit that is a descendant of a commit
+that the old tag v1.2.3 points at.  This was found to be error prone
+and starting with this release, any attempt to update an existing
+ref under refs/tags/ hierarchy will fail, without "--force".
+
+When "git add -u" and "git add -A" that does not specify what paths
+to add on the command line is run from inside a subdirectory, the
+scope of the operation has always been limited to the subdirectory.
+Many users found this counter-intuitive, given that "git commit -a"
+and other commands operate on the entire tree regardless of where you
+are.  In this release, these commands give a warning message that
+suggests the users to use "git add -u/-A ." when they want to limit
+the scope to the current directory; doing so will squelch the message,
+while training their fingers.
+
+
+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics that pushes the current branch to the branch with the same
+name, only when the current branch is set to integrate with that
+remote branch.  There is a user preference configuration variable
+"push.default" to change this.  If you are an old-timer who is used
+to the "matching" semantics, you can set it to "matching" to keep the
+traditional behaviour.  If you want to live in the future early,
+you can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" and "git add -A", that does not specify what paths
+to add on the command line is run from inside a subdirectory, these
+commands will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands. Because there will be no
+mechanism to make "git add -u" behave as if "git add -u .", it is
+important for those who are used to "git add -u" (without pathspec)
+updating the index only for paths in the current subdirectory to start
+training their fingers to explicitly say "git add -u ." when they mean
+it before Git 2.0 comes.
+
+
+Updates since v1.8.1
+--------------------
+
+UI, Workflows & Features
+
+ * Initial ports to QNX and z/OS UNIX System Services have started.
+
+ * Output from the tests is coloured using "green is okay, yellow is
+   questionable, red is bad and blue is informative" scheme.
+
+ * Mention of "GIT/Git/git" in the documentation have been updated to
+   be more uniform and consistent.  The name of the system and the
+   concept it embodies is "Git"; the command the users type is "git".
+   All-caps "GIT" was merely a way to imitate "Git" typeset in small
+   caps in our ASCII text only documentation and to be avoided.
+
+ * The completion script (in contrib/completion) used to let the
+   default completer to suggest pathnames, which gave too many
+   irrelevant choices (e.g. "git add" would not want to add an
+   unmodified path).  It learnt to use a more git-aware logic to
+   enumerate only relevant ones.
+
+ * In bare repositories, "git shortlog" and other commands now read
+   mailmap files from the tip of the history, to help running these
+   tools in server settings.
+
+ * Color specifiers, e.g. "%C(blue)Hello%C(reset)", used in the
+   "--format=" option of "git log" and friends can be disabled when
+   the output is not sent to a terminal by prefixing them with
+   "auto,", e.g. "%C(auto,blue)Hello%C(auto,reset)".
+
+ * Scripts can ask Git that wildcard patterns in pathspecs they give do
+   not have any significance, i.e. take them as literal strings.
+
+ * The patterns in .gitignore and .gitattributes files can have **/,
+   as a pattern that matches 0 or more levels of subdirectory.
+   E.g. "foo/**/bar" matches "bar" in "foo" itself or in a
+   subdirectory of "foo".
+
+ * When giving arguments without "--" disambiguation, object names
+   that come earlier on the command line must not be interpretable as
+   pathspecs and pathspecs that come later on the command line must
+   not be interpretable as object names.  This disambiguation rule has
+   been tweaked so that ":/" (no other string before or after) is
+   always interpreted as a pathspec; "git cmd -- :/" is no longer
+   needed, you can just say "git cmd :/".
+
+ * Various "hint" lines Git gives when it asks the user to edit
+   messages in the editor are commented out with '#' by default. The
+   core.commentchar configuration variable can be used to customize
+   this '#' to a different character.
+
+ * "git add -u" and "git add -A" without pathspec issues warning to
+   make users aware that they are only operating on paths inside the
+   subdirectory they are in.  Use ":/" (everything from the top) or
+   "." (everything from the $cwd) to disambiguate.
+
+ * "git blame" (and "git diff") learned the "--no-follow" option.
+
+ * "git branch" now rejects some nonsense combinations of command line
+   arguments (e.g. giving more than one branch name to rename) with
+   more case-specific error messages.
+
+ * "git check-ignore" command to help debugging .gitignore files has
+   been added.
+
+ * "git cherry-pick" can be used to replay a root commit to an unborn
+   branch.
+
+ * "git commit" can be told to use --cleanup=whitespace by setting the
+   configuration variable commit.cleanup to 'whitespace'.
+
+ * "git diff" and other Porcelain commands can be told to use a
+   non-standard algorithm by setting diff.algorithm configuration
+   variable.
+
+ * "git fetch --mirror" and fetch that uses other forms of refspec
+   with wildcard used to attempt to update a symbolic ref that match
+   the wildcard on the receiving end, which made little sense (the
+   real ref that is pointed at by the symbolic ref would be updated
+   anyway).  Symbolic refs no longer are affected by such a fetch.
+
+ * "git format-patch" now detects more cases in which a whole branch
+   is being exported, and uses the description for the branch, when
+   asked to write a cover letter for the series.
+
+ * "git format-patch" learned "-v $count" option, and prepends a
+   string "v$count-" to the names of its output files, and also
+   automatically sets the subject prefix to "PATCH v$count". This
+   allows patches from rerolled series to be stored under different
+   names and makes it easier to reuse cover letter messages.
+
+ * "git log" and friends can be told with --use-mailmap option to
+   rewrite the names and email addresses of people using the mailmap
+   mechanism.
+
+ * "git log --cc --graph" now shows the combined diff output with the
+   ancestry graph.
+
+ * "git log --grep=<pattern>" honors i18n.logoutputencoding to look
+   for the pattern after fixing the log message to the specified
+   encoding.
+
+ * "git mergetool" and "git difftool" learned to list the available
+   tool backends in a more consistent manner.
+
+ * "git mergetool" is aware of TortoiseGitMerge now and uses it over
+   TortoiseMerge when available.
+
+ * "git push" now requires "-f" to update a tag, even if it is a
+   fast-forward, as tags are meant to be fixed points.
+
+ * Error messages from "git push" when it stops to prevent remote refs
+   from getting overwritten by mistake have been improved to explain
+   various situations separately.
+
+ * "git push" will stop without doing anything if the new "pre-push"
+   hook exists and exits with a failure.
+
+ * When "git rebase" fails to generate patches to be applied (e.g. due
+   to oom), it failed to detect the failure and instead behaved as if
+   there were nothing to do.  A workaround to use a temporary file has
+   been applied, but we probably would want to revisit this later, as
+   it hurts the common case of not failing at all.
+
+ * Input and preconditions to "git reset" has been loosened where
+   appropriate.  "git reset $fromtree Makefile" requires $fromtree to
+   be any tree (it used to require it to be a commit), for example.
+   "git reset" (without options or parameters) used to error out when
+   you do not have any commits in your history, but it now gives you
+   an empty index (to match non-existent commit you are not even on).
+
+ * "git status" says what branch is being bisected or rebased when
+   able, not just "bisecting" or "rebasing".
+
+ * "git submodule" started learning a new mode to integrate with the
+   tip of the remote branch (as opposed to integrating with the commit
+   recorded in the superproject's gitlink).
+
+ * "git upload-pack" which implements the service "ls-remote" and
+   "fetch" talk to can be told to hide ref hierarchies the server
+   side internally uses (and that clients have no business learning
+   about) with transfer.hiderefs configuration.
+
+
+Foreign Interface
+
+ * "git fast-export" has been updated for its use in the context of
+   the remote helper interface.
+
+ * A new remote helper to interact with bzr has been added to contrib/.
+
+ * "git p4" got various bugfixes around its branch handling.  It is
+   also made usable with Python 2.4/2.5.  In addition, its various
+   portability issues for Cygwin have been addressed.
+
+ * The remote helper to interact with Hg in contrib/ has seen a few
+   fixes.
+
+
+Performance, Internal Implementation, etc.
+
+ * "git fsck" has been taught to be pickier about entries in tree
+   objects that should not be there, e.g. ".", ".git", and "..".
+
+ * Matching paths with common forms of pathspecs that contain wildcard
+   characters has been optimized further.
+
+ * We stopped paying attention to $GIT_CONFIG environment that points
+   at a single configuration file from any command other than "git config"
+   quite a while ago, but "git clone" internally set, exported, and
+   then unexported the variable during its operation unnecessarily.
+
+ * "git reset" internals has been reworked and should be faster in
+   general. We tried to be careful not to break any behaviour but
+   there could be corner cases, especially when running the command
+   from a conflicted state, that we may have missed.
+
+ * The implementation of "imap-send" has been updated to reuse xml
+   quoting code from http-push codepath, and lost a lot of unused
+   code.
+
+ * There is a simple-minded checker for the test scripts in t/
+   directory to catch most common mistakes (it is not enabled by
+   default).
+
+ * You can build with USE_WILDMATCH=YesPlease to use a replacement
+   implementation of pattern matching logic used for pathname-like
+   things, e.g. refnames and paths in the repository.  This new
+   implementation is not expected change the existing behaviour of Git
+   in this release, except for "git for-each-ref" where you can now
+   say "refs/**/master" and match with both refs/heads/master and
+   refs/remotes/origin/master.  We plan to use this new implementation
+   in wider places (e.g. "git ls-files '**/Makefile' may find Makefile
+   at the top-level, and "git log '**/t*.sh'" may find commits that
+   touch a shell script whose name begins with "t" at any level) in
+   future versions of Git, but we are not there yet.  By building with
+   USE_WILDMATCH, using the resulting Git daily and reporting when you
+   find breakages, you can help us get closer to that goal.
+
+ * Some reimplementations of Git do not write all the stat info back
+   to the index due to their implementation limitations (e.g. jgit).
+   A configuration option can tell Git to ignore changes to most of
+   the stat fields and only pay attention to mtime and size, which
+   these implementations can reliably update.  This can be used to
+   avoid excessive revalidation of contents.
+
+ * Some platforms ship with old version of expat where xmlparse.h
+   needs to be included instead of expat.h; the build procedure has
+   been taught about this.
+
+ * "make clean" on platforms that cannot compute header dependencies
+   on the fly did not work with implementations of "rm" that do not
+   like an empty argument list.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.8.1
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.1 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * An element on GIT_CEILING_DIRECTORIES list that does not name the
+   real path to a directory (i.e. a symbolic link) could have caused
+   the GIT_DIR discovery logic to escape the ceiling.
+
+ * When attempting to read the XDG-style $HOME/.config/git/config and
+   finding that $HOME/.config/git is a file, we gave a wrong error
+   message, instead of treating the case as "a custom config file does
+   not exist there" and moving on.
+
+ * The behaviour visible to the end users was confusing, when they
+   attempt to kill a process spawned in the editor that was in turn
+   launched by Git with SIGINT (or SIGQUIT), as Git would catch that
+   signal and die.  We ignore these signals now.
+   (merge 0398fc34 pf/editor-ignore-sigint later to maint).
+
+ * A child process that was killed by a signal (e.g. SIGINT) was
+   reported in an inconsistent way depending on how the process was
+   spawned by us, with or without a shell in between.
+
+ * After failing to create a temporary file using mkstemp(), failing
+   pathname was not reported correctly on some platforms.
+
+ * We used to stuff "user@" and then append what we read from
+   /etc/mailname to come up with a default e-mail ident, but a bug
+   lost the "user@" part.
+
+ * The attribute mechanism didn't allow limiting attributes to be
+   applied to only a single directory itself with "path/" like the
+   exclude mechanism does.  The initial implementation of this that
+   was merged to 'maint' and 1.8.1.2 was with a severe performance
+   degradations and needs to merge a fix-up topic.
+
+ * The smart HTTP clients forgot to verify the content-type that comes
+   back from the server side to make sure that the request is being
+   handled properly.
+
+ * "git am" did not parse datestamp correctly from Hg generated patch,
+   when it is run in a locale outside C (or en).
+
+ * "git apply" misbehaved when fixing whitespace breakages by removing
+   excess trailing blank lines.
+
+ * "git apply --summary" has been taught to make sure the similarity
+   value shown in its output is sensible, even when the input had a
+   bogus value.
+
+ * A tar archive created by "git archive" recorded a directory in a
+   way that made NetBSD's implementation of "tar" sometimes unhappy.
+
+ * "git archive" did not record uncompressed size in the header when
+   streaming a zip archive, which confused some implementations of unzip.
+
+ * "git archive" did not parse configuration values in tar.* namespace
+   correctly.
+   (merge b3873c3 jk/config-parsing-cleanup later to maint).
+
+ * Attempt to "branch --edit-description" an existing branch, while
+   being on a detached HEAD, errored out.
+
+ * "git clean" showed what it was going to do, but sometimes end up
+   finding that it was not allowed to do so, which resulted in a
+   confusing output (e.g. after saying that it will remove an
+   untracked directory, it found an embedded git repository there
+   which it is not allowed to remove).  It now performs the actions
+   and then reports the outcome more faithfully.
+
+ * When "git clone --separate-git-dir=$over_there" is interrupted, it
+   failed to remove the real location of the $GIT_DIR it created.
+   This was most visible when interrupting a submodule update.
+
+ * "git cvsimport" mishandled timestamps at DST boundary.
+
+ * We used to have an arbitrary 32 limit for combined diff input,
+   resulting in incorrect number of leading colons shown when showing
+   the "--raw --cc" output.
+
+ * "git fetch --depth" was broken in at least three ways.  The
+   resulting history was deeper than specified by one commit, it was
+   unclear how to wipe the shallowness of the repository with the
+   command, and documentation was misleading.
+   (merge cfb70e1 nd/fetch-depth-is-broken later to maint).
+
+ * "git log --all -p" that walked refs/notes/textconv/ ref can later
+   try to use the textconv data incorrectly after it gets freed.
+
+ * We forgot to close the file descriptor reading from "gpg" output,
+   killing "git log --show-signature" on a long history.
+
+ * The way "git svn" asked for password using SSH_ASKPASS and
+   GIT_ASKPASS was not in line with the rest of the system.
+
+ * The --graph code fell into infinite loop when asked to do what the
+   code did not expect.
+
+ * http transport was wrong to ask for the username when the
+   authentication is done by certificate identity.
+
+ * "git pack-refs" that ran in parallel to another process that
+   created new refs had a nasty race.
+
+ * Rebasing the history of superproject with change in the submodule
+   has been broken since v1.7.12.
+
+ * After "git add -N" and then writing a tree object out of the
+   index, the cache-tree data structure got corrupted.
+
+ * "git clone" used to allow --bare and --separate-git-dir=$there
+   options at the same time, which was nonsensical.
+
+ * "git rebase --preserve-merges" lost empty merges in recent versions
+   of Git.
+
+ * "git merge --no-edit" computed who were involved in the work done
+   on the side branch, even though that information is to be discarded
+   without getting seen in the editor.
+
+ * "git merge" started calling prepare-commit-msg hook like "git
+   commit" does some time ago, but forgot to pay attention to the exit
+   status of the hook.
+
+ * A failure to push due to non-ff while on an unborn branch
+   dereferenced a NULL pointer when showing an error message.
+
+ * When users spell "cc:" in lowercase in the fake "header" in the
+   trailer part, "git send-email" failed to pick up the addresses from
+   there. As e-mail headers field names are case insensitive, this
+   script should follow suit and treat "cc:" and "Cc:" the same way.
+
+ * Output from "git status --ignored" showed an unexpected interaction
+   with "--untracked".
+
+ * "gitweb", when sorting by age to show repositories with new
+   activities first, used to sort repositories with absolutely
+   nothing in it early, which was not very useful.
+
+ * "gitweb"'s code to sanitize control characters before passing it to
+   "highlight" filter lost known-to-be-safe control characters by
+   mistake.
+
+ * "gitweb" pages served over HTTPS, when configured to show picon or
+   gravatar, referred to these external resources to be fetched via
+   HTTP, resulting in mixed contents warning in browsers.
+
+ * When a line to be wrapped has a solid run of non space characters
+   whose length exactly is the wrap width, "git shortlog -w" failed
+   to add a newline after such a line.
+
+ * Command line completion leaked an unnecessary error message while
+   looking for possible matches with paths in <tree-ish>.
+
+ * Command line completion for "tcsh" emitted an unwanted space
+   after completing a single directory name.
+
+ * Command line completion code was inadvertently made incompatible with
+   older versions of bash by using a newer array notation.
+
+ * "git push" was taught to refuse updating the branch that is
+   currently checked out long time ago, but the user manual was left
+   stale.
+   (merge 50995ed wk/man-deny-current-branch-is-default-these-days later to maint).
+
+ * Some shells do not behave correctly when IFS is unset; work it
+   around by explicitly setting it to the default value.
+
+ * Some scripted programs written in Python did not get updated when
+   PYTHON_PATH changed.
+   (cherry-pick 96a4647fca54031974cd6ad1 later to maint).
+
+ * When autoconf is used, any build on a different commit always ran
+   "config.status --recheck" even when unnecessary.
+
+ * A fix was added to the build procedure to work around buggy
+   versions of ccache broke the auto-generation of dependencies, which
+   unfortunately is still relevant because some people use ancient
+   distros.
+
+ * The autoconf subsystem passed --mandir down to generated
+   config.mak.autogen but forgot to do the same for --htmldir.
+   (merge 55d9bf0 ct/autoconf-htmldir later to maint).
+
+ * A change made on v1.8.1.x maintenance track had a nasty regression
+   to break the build when autoconf is used.
+   (merge 7f1b697 jn/less-reconfigure later to maint).
+
+ * We have been carrying a translated and long-unmaintained copy of an
+   old version of the tutorial; removed.
+
+ * t0050 had tests expecting failures from a bug that was fixed some
+   time ago.
+
+ * t4014, t9502 and t0200 tests had various portability issues that
+   broke on OpenBSD.
+
+ * t9020 and t3600 tests had various portability issues.
+
+ * t9200 runs "cvs init" on a directory that already exists, but a
+   platform can configure this fail for the current user (e.g. you
+   need to be in the cvsadmin group on NetBSD 6.0).
+
+ * t9020 and t9810 had a few non-portable shell script construct.
+
+ * Scripts to test bash completion was inherently flaky as it was
+   affected by whatever random things the user may have on $PATH.
+
+ * An element on GIT_CEILING_DIRECTORIES could be a "logical" pathname
+   that uses a symbolic link to point at somewhere else (e.g. /home/me
+   that points at /net/host/export/home/me, and the latter directory
+   is automounted). Earlier when Git saw such a pathname e.g. /home/me
+   on this environment variable, the "ceiling" mechanism did not take
+   effect. With this release (the fix has also been merged to the
+   v1.8.1.x maintenance series), elements on GIT_CEILING_DIRECTORIES
+   are by default checked for such aliasing coming from symbolic
+   links. As this needs to actually resolve symbolic links for each
+   element on the GIT_CEILING_DIRECTORIES, you can disable this
+   mechanism for some elements by listing them after an empty element
+   on the GIT_CEILING_DIRECTORIES. e.g. Setting /home/me::/home/him to
+   GIT_CEILING_DIRECTORIES makes Git resolve symbolic links in
+   /home/me when checking if the current directory is under /home/me,
+   but does not do so for /home/him.
+   (merge 7ec30aa mh/maint-ceil-absolute later to maint).

+Git v1.8.3.1 Release Notes
+========================
+
+Fixes since v1.8.3
+------------------
+
+ * When $HOME is misconfigured to point at an unreadable directory, we
+   used to complain and die. The check has been loosened.
+
+ * Handling of negative exclude pattern for directories "!dir" was
+   broken in the update to v1.8.3.
+

+Git v1.8.3.2 Release Notes
+==========================
+
+Fixes since v1.8.3.1
+--------------------
+
+ * Cloning with "git clone --depth N" while fetch.fsckobjects (or
+   transfer.fsckobjects) is set to true did not tell the cut-off
+   points of the shallow history to the process that validates the
+   objects and the history received, causing the validation to fail.
+
+ * "git checkout foo" DWIMs the intended "upstream" and turns it into
+   "git checkout -t -b foo remotes/origin/foo". This codepath has been
+   updated to correctly take existing remote definitions into account.
+
+ * "git fetch" into a shallow repository from a repository that does
+   not know about the shallow boundary commits (e.g. a different fork
+   from the repository the current shallow repository was cloned from)
+   did not work correctly.
+
+ * "git subtree" (in contrib/) had one codepath with loose error
+   checks to lose data at the remote side.
+
+ * "git log --ancestry-path A...B" did not work as expected, as it did
+   not pay attention to the fact that the merge base between A and B
+   was the bottom of the range being specified.
+
+ * "git diff -c -p" was not showing a deleted line from a hunk when
+   another hunk immediately begins where the earlier one ends.
+
+ * "git merge @{-1}~22" was rewritten to "git merge frotz@{1}~22"
+   incorrectly when your previous branch was "frotz" (it should be
+   rewritten to "git merge frotz~22" instead).
+
+ * "git commit --allow-empty-message -m ''" should not start an
+   editor.
+
+ * "git push --[no-]verify" was not documented.
+
+ * An entry for "file://" scheme in the enumeration of URL types Git
+   can take in the HTML documentation was made into a clickable link
+   by mistake.
+
+ * zsh prompt script that borrowed from bash prompt script did not
+   work due to slight differences in array variable notation between
+   these two shells.
+
+ * The bash prompt code (in contrib/) displayed the name of the branch
+   being rebased when "rebase -i/-m/-p" modes are in use, but not the
+   plain vanilla "rebase".
+
+ * "git push $there HEAD:branch" did not resolve HEAD early enough, so
+   it was easy to flip it around while push is still going on and push
+   out a branch that the user did not originally intended when the
+   command was started.
+
+ * "difftool --dir-diff" did not copy back changes made by the
+   end-user in the diff tool backend to the working tree in some
+   cases.

+Git v1.8.3.3 Release Notes
+==========================
+
+Fixes since v1.8.3.2
+--------------------
+
+ * "git apply" parsed patches that add new files, generated by programs
+   other than Git, incorrectly.  This is an old breakage in v1.7.11.
+
+ * Older cURL wanted piece of memory we call it with to be stable, but
+   we updated the auth material after handing it to a call.
+
+ * "git pull" into nothing trashed "local changes" that were in the
+   index.
+
+ * Many "git submodule" operations did not work on a submodule at a
+   path whose name is not in ASCII.
+
+ * "cherry-pick" had a small leak in its error codepath.
+
+ * Logic used by git-send-email to suppress cc mishandled names like
+   "A U. Thor" <author@example.xz>, where the human readable part
+   needs to be quoted (the user input may not have the double quotes
+   around the name, and comparison was done between quoted and
+   unquoted strings).  It also mishandled names that need RFC2047
+   quoting.
+
+ * "gitweb" forgot to clear a global variable $search_regexp upon each
+   request, mistakenly carrying over the previous search to a new one
+   when used as a persistent CGI.
+
+ * The wildmatch engine did not honor WM_CASEFOLD option correctly.
+
+ * "git log -c --follow $path" segfaulted upon hitting the commit that
+   renamed the $path being followed.
+
+ * When a reflog notation is used for implicit "current branch",
+   e.g. "git log @{u}", we did not say which branch and worse said
+   "branch ''" in the error messages.
+
+ * Mac OS X does not like to write(2) more than INT_MAX number of
+   bytes; work it around by chopping write(2) into smaller pieces.
+
+ * Newer MacOS X encourages the programs to compile and link with
+   their CommonCrypto, not with OpenSSL.
+
+Also contains various minor documentation updates.

+========================

+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics that pushes only the current branch to the branch with the same
+name, and only when the current branch is set to integrate with that
+remote branch.  Use the user preference configuration variable
+"push.default" to change this.  If you are an old-timer who is used
+to the "matching" semantics, you can set the variable to "matching"
+to keep the traditional behaviour.  If you want to live in the future
+early, you can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands.  There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes.  A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal.  Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+
+Updates since v1.8.2
+--------------------
+
+Foreign interface
+
+ * remote-hg and remote-bzr helpers (in contrib/ since v1.8.2) have
+   been updated; especially, the latter has been done in an
+   accelerated schedule (read: we may not have merged to this release
+   if we were following the usual "cook sufficiently in next before
+   unleashing it to the world" workflow) in order to help Emacs folks,
+   whose primary SCM seems to be stagnating.
+
+
+UI, Workflows & Features
+
+ * A handful of updates applied to gitk, including an addition of
+   "revert" action, showing dates in tags in a nicer way, making
+   colors configurable, and support for -G'pickaxe' search.
+
+ * The prompt string generator (in contrib/completion/) learned to
+   show how many changes there are in total and how many have been
+   replayed during a "git rebase" session.
+
+ * "git branch --vv" learned to paint the name of the branch it
+   integrates with in a different color (color.branch.upstream,
+   which defaults to blue).
+
+ * In a sparsely populated working tree, "git checkout <pathspec>" no
+   longer unmarks paths that match the given pathspec that were
+   originally ignored with "--sparse" (use --ignore-skip-worktree-bits
+   option to resurrect these paths out of the index if you really want
+   to).
+
+ * "git log --format" specifier learned %C(auto) token that tells Git
+   to use color when interpolating %d (decoration), %h (short commit
+   object name), etc. for terminal output.
+
+ * "git bisect" leaves the final outcome as a comment in its bisect
+   log file.
+
+ * "git clone --reference" can now refer to a gitfile "textual symlink"
+   that points at the real location of the repository.
+
+ * "git count-objects" learned "--human-readable" aka "-H" option to
+   show various large numbers in Ki/Mi/GiB scaled as necessary.
+
+ * "git cherry-pick $blob" and "git cherry-pick $tree" are nonsense,
+   and a more readable error message e.g. "can't cherry-pick a tree"
+   is given (we used to say "expected exactly one commit").
+
+ * The "--annotate" option to "git send-email" can be turned on (or
+   off) by default with sendemail.annotate configuration variable (you
+   can use --no-annotate from the command line to override it).
+
+ * The "--cover-letter" option to "git format-patch" can be turned on
+   (or off) by default with format.coverLetter configuration
+   variable. By setting it to 'auto', you can turn it on only for a
+   series with two or more patches.
+
+ * The bash completion support (in contrib/) learned that cherry-pick
+   takes a few more options than it already knew about.
+
+ * "git help" learned "-g" option to show the list of guides just like
+   list of commands are given with "-a".
+
+ * A triangular "pull from one place, push to another place" workflow
+   is supported better by new remote.pushdefault (overrides the
+   "origin" thing) and branch.*.pushremote (overrides the
+   branch.*.remote) configuration variables.
+
+ * "git status" learned to report that you are in the middle of a
+   revert session, just like it does for a cherry-pick and a bisect
+   session.
+
+ * The handling by "git branch --set-upstream-to" against various forms
+   of erroneous inputs was suboptimal and has been improved.
+
+ * When the interactive access to git-shell is not enabled, it issues
+   a message meant to help the system administrator to enable it.  An
+   explicit way has been added to issue custom messages to refuse an
+   access over the network to help the end users who connect to the
+   service expecting an interactive shell.
+
+ * In addition to the case where the user edits the log message with
+   the "e)dit" option of "am -i", replace the "Applying: this patch"
+   message with the final log message contents after applymsg hook
+   munges it.
+
+ * "git status" suggests users to look into using --untracked=no option
+   when it takes too long.
+
+ * "git status" shows a bit more information during a rebase/bisect
+   session.
+
+ * "git fetch" learned to fetch a commit at the tip of an unadvertised
+   ref by specifying a raw object name from the command line when the
+   server side supports this feature.
+
+ * Output from "git log --graph" works better with submodule log
+   output now.
+
+ * "git count-objects -v" learned to report leftover temporary
+   packfiles and other garbage in the object store.
+
+ * A new read-only credential helper (in contrib/) to interact with
+   the .netrc/.authinfo files has been added.
+
+ * "git send-email" can be used with the credential helper system.
+
+ * There was no Porcelain way to say "I no longer am interested in
+   this submodule", once you express your interest in a submodule with
+   "submodule init".  "submodule deinit" is the way to do so.
+
+ * "git pull --rebase" learned to pass "-v/-q" options to underlying
+   "git rebase".
+
+ * The new "--follow-tags" option tells "git push" to push relevant
+   annotated tags when pushing branches out.
+
+ * "git merge" and "git pull" can optionally be told to inspect and
+   reject when merging a commit that does not carry a trusted GPG
+   signature.
+
+ * "git mergetool" now feeds files to the "p4merge" backend in the
+   order that matches the p4 convention, where "theirs" is usually
+   shown on the left side, which is the opposite from what other backends
+   expect.
+
+ * "show/log" now honors gpg.program configuration just like other
+   parts of the code that use GnuPG.
+
+ * "git log" that shows the difference between the parent and the
+   child has been optimized somewhat.
+
+ * "git difftool" allows the user to write into the temporary files
+   being shown; if the user makes changes to the working tree at the
+   same time, it now refrains from overwriting the copy in the working
+   tree and leaves the temporary file so that changes can be merged
+   manually.
+
+ * There was no good way to ask "I have a random string that came from
+   outside world. I want to turn it into a 40-hex object name while
+   making sure such an object exists".  A new peeling suffix ^{object}
+   can be used for that purpose, together with "rev-parse --verify".
+
+
+Performance, Internal Implementation, etc.
+
+ * Updates for building under msvc.
+
+ * A handful of issues in the code that traverses the working tree to find
+   untracked and/or ignored files have been fixed, and the general
+   codepath involved in "status -u" and "clean" have been cleaned up
+   and optimized.
+
+ * The stack footprint of some codepaths that access an object from a
+   pack has been shrunk.
+
+ * The logic to coalesce the same lines removed from the parents in
+   the output from "diff -c/--cc" has been updated, but with O(n^2)
+   complexity, so this might turn out to be undesirable.
+
+ * The code to enforce permission bits on files in $GIT_DIR/ for
+   shared repositories has been simplified.
+
+ * A few codepaths know how much data they need to put in the
+   hashtables they use when they start, but still began with small tables
+   and repeatedly grew and rehashed them.
+
+ * The API to walk reflog entries from the latest to older, which was
+   necessary for operations such as "git checkout -", was cumbersome
+   to use correctly and also inefficient.
+
+ * Codepaths that inspect log-message-to-be and decide when to add a
+   new Signed-off-by line in various commands have been consolidated.
+
+ * The pkt-line API, implementation and its callers have been cleaned
+   up to make them more robust.
+
+ * The Cygwin port has a faster-but-lying lstat(2) emulation whose
+   incorrectness does not matter in practice except for a few
+   codepaths, and setting permission bits on directories is a codepath
+   that needs to use a more correct one.
+
+ * "git checkout" had repeated pathspec matches on the same paths,
+   which have been consolidated.  Also a bug in "git checkout dir/"
+   that is started from an unmerged index has been fixed.
+
+ * A few bugfixes to "git rerere" working on corner case merge
+   conflicts have been applied.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.2
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.2 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * Recent versions of File::Temp (used by "git svn") started blowing
+   up when its tempfile sub is called as a class method; updated the
+   callsite to call it as a plain vanilla function to fix it.
+   (merge eafc2dd hb/git-pm-tempfile later to maint).
+
+ * Various subcommands of "git remote" simply ignored extraneous
+   command line arguments instead of diagnosing them as errors.
+
+ * When receive-pack detects an error in the pack header it received in
+   order to decide which of unpack-objects or index-pack to run, it
+   returned without closing the error stream, which led to a hung
+   sideband thread.
+
+ * Zsh completion forgot that the '%' character used to signal untracked
+   files needs to be escaped with another '%'.
+
+ * A commit object whose author or committer ident are malformed
+   crashed some code that trusted that a name, an email and a
+   timestamp can always be found in it.
+
+ * When "upload-pack" fails while generating a pack in response to
+   "git fetch" (or "git clone"), the receiving side had
+   a programming error that triggered the die handler
+   recursively.
+
+ * "rev-list --stdin" and friends kept bogus pointers into the input
+   buffer around as human readable object names.  This was not a huge
+   problem but was exposed by a new change that uses these names in
+   error output.
+
+ * Smart-capable HTTP servers were not restricted via the
+   GIT_NAMESPACE mechanism when talking with commit-walking clients,
+   like they are when talking with smart HTTP clients.
+   (merge 6130f86 jk/http-dumb-namespaces later to maint).
+
+ * "git merge-tree" did not omit a merge result that is identical to
+   the "our" side in certain cases.
+   (merge aacecc3 jk/merge-tree-added-identically later to maint).
+
+ * Perl scripts like "git-svn" closed (instead of redirecting to /dev/null)
+   the standard error stream, which is not a very smart thing to do.
+   A later open may return file descriptor #2 for an unrelated purpose, and
+   error reporting code may write into it.
+
+ * "git show-branch" was not prepared to show a very long run of
+   ancestor operators e.g. foobar^2~2^2^2^2...^2~4 correctly.
+
+ * "git diff --diff-algorithm algo" is also understood as "git diff
+   --diff-algorithm=algo".
+
+ * The new core.commentchar configuration was not applied in a few
+   places.
+
+ * "git bundle" erroneously bailed out when parsing a valid bundle
+   containing a prerequisite commit without a commit message.
+
+ * "git log -S/-G" started paying attention to textconv filter, but
+   there was no way to disable this.  Make it honor the --no-textconv
+   option.
+
+ * When used with the "-d temporary-directory" option, "git filter-branch"
+   failed to come back to the original working tree to perform the
+   final clean-up procedure.
+
+ * "git merge $(git rev-parse v1.8.2)" behaved quite differently from
+   "git merge v1.8.2", as if v1.8.2 were written as v1.8.2^0 and did
+   not pay much attention to the annotated tag payload.  Make the code
+   notice the type of the tag object, in addition to the dwim_ref()
+   based classification the current code uses (i.e. the name appears
+   in refs/tags/) to decide when to special-case tag merging.
+
+ * Fix a 1.8.1.x regression that stopped matching "dir" (without a
+   trailing slash) to a directory "dir".
+
+ * "git apply --whitespace=fix" was not prepared to see a line getting
+   longer after fixing whitespaces (e.g. tab-in-indent aka Python).
+
+ * The prompt string generator (in contrib/completion/) did not notice
+   when we are in a middle of a "git revert" session.
+
+ * "submodule summary --summary-limit" option did not support the
+   "--option=value" form.
+
+ * "index-pack --fix-thin" used an uninitialized value to compute
+   the delta depths of objects it appends to the resulting pack.
+
+ * "index-pack --verify-stat" used a few counters outside the protection
+   of a mutex, possibly showing incorrect numbers.
+
+ * The code to keep track of what directory names are known to Git on
+   platforms with case insensitive filesystems could get confused upon a
+   hash collision between these pathnames and would loop forever.
+
+ * Annotated tags outside the refs/tags/ hierarchy were not advertised
+   correctly to ls-remote and fetch with recent versions of Git.
+
+ * Recent optimizations broke shallow clones.
+
+ * "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and
+   instead the parser kept reading beyond the end of the string.
+
+ * "git tag -f <tag>" always said "Updated tag '<tag>'" even when
+   creating a new tag (i.e. neither overwriting nor updating).
+
+ * "git p4" did not behave well when the path to the root of the P4
+   client was not its real path.
+   (merge bbd8486 pw/p4-symlinked-root later to maint).
+
+ * "git archive" reported a failure when asked to create an archive out
+   of an empty tree.  It is more intuitive to give an empty
+   archive back in such a case.
+
+ * When "format-patch" quoted a non-ascii string in header files,
+   it incorrectly applied rfc2047 and chopped a single character in
+   the middle of the string.
+
+ * An aliased command spawned from a bare repository that does not say
+   it is bare with "core.bare = yes" was treated as non-bare by mistake.
+
+ * In "git reflog expire", the REACHABLE bit was not cleared from the
+   correct objects.
+
+ * The logic used by "git diff -M --stat" to shorten the names of
+   files before and after a rename did not work correctly when the
+   common prefix and suffix between the two filenames overlapped.
+
+ * The "--match=<pattern>" option of "git describe", when used with
+   "--all" to allow refs that are not annotated tags to be a
+   base of description, did not restrict the output from the command
+   to those refs that match the given pattern.
+
+ * Clarify in the documentation "what" gets pushed to "where" when the
+   command line to "git push" does not say these explicitly.
+
+ * The "--color=<when>" argument to the commands in the diff family
+   was described poorly.
+
+ * The arguments given to the pre-rebase hook were not documented.
+
+ * The v4 index format was not documented.
+
+ * The "--match=<pattern>" argument "git describe" takes uses glob
+   pattern but it wasn't obvious from the documentation.
+
+ * Some sources failed to compile on systems that lack NI_MAXHOST in
+   their system header (e.g. z/OS).
+
+ * Add an example use of "--env-filter" in "filter-branch"
+   documentation.
+
+ * "git bundle verify" did not say "records a complete history" for a
+   bundle that does not have any prerequisites.
+
+ * In the v1.8.0 era, we changed symbols that do not have to be global
+   to file scope static, but a few functions in graph.c were used by
+   CGit sideways, bypassing the entry points of the API the
+   in-tree users use.
+
+ * "git update-index -h" did not do the usual "-h(elp)" thing.
+
+ * "git index-pack" had a buffer-overflow while preparing an
+   informational message when the translated version of it was too
+   long.
+
+ * 'git commit -m "$msg"' used to add an extra newline even when
+   $msg already ended with one.
+
+ * The SSL peer verification done by "git imap-send" did not ask for
+   Server Name Indication (RFC 4366), failing to connect to SSL/TLS
+   sites that serve multiple hostnames on a single IP.
+
+ * perl/Git.pm::cat_blob slurped everything in core only to write it
+   out to a file descriptor, which was not a very smart thing to do.
+
+ * "git branch" did not bother to check nonsense command line
+   parameters.  It now issues errors in many cases.
+
+ * Verification of signed tags was not done correctly when not in C
+   or en/US locale.
+
+ * Some platforms and users spell UTF-8 differently; retry with the
+   most official "UTF-8" when the system does not understand the
+   user-supplied encoding name that is a common alternative
+   spelling of UTF-8.
+
+ * When export-subst is used, "zip" output recorded an incorrect
+   size of the file.
+
+ * "git am $maildir/" applied messages in an unexpected order; sort
+   filenames read from the maildir/ in a way that is more likely to
+   sort the messages in the order the writing MUA meant to, by sorting
+   numeric segments in numeric order and non-numeric segments in
+   alphabetical order.
+
+ * "git submodule update", when recursed into sub-submodules, did not
+   accumulate the prefix paths.

+Git v1.8.4.1 Release Notes
+========================
+
+Fixes since v1.8.4
+------------------
+
+ * Some old versions of bash do not grok some constructs like
+   'printf -v varname' which the prompt and completion code started
+   to use recently.  The completion and prompt scripts have been
+   adjusted to work better with these old versions of bash.
+
+ * In FreeBSD's and NetBSD's "sh", a return in a dot script in a
+   function returns from the function, not only in the dot script,
+   breaking "git rebase" on these platforms (regression introduced
+   in 1.8.4-rc1).
+
+ * "git rebase -i" and other scripted commands were feeding a
+   random, data dependant error message to 'echo' and expecting it
+   to come out literally.
+
+ * Setting the "submodule.<name>.path" variable to the empty
+   "true" caused the configuration parser to segfault.
+
+ * Output from "git log --full-diff -- <pathspec>" looked strange
+   because comparison was done with the previous ancestor that
+   touched the specified <pathspec>, causing the patches for paths
+   outside the pathspec to show more than the single commit has
+   changed.
+
+ * The auto-tag-following code in "git fetch" tries to reuse the
+   same transport twice when the serving end does not cooperate and
+   does not give tags that point to commits that are asked for as
+   part of the primary transfer.  Unfortunately, Git-aware transport
+   helper interface is not designed to be used more than once, hence
+   this did not work over smart-http transfer.  Fixed.
+
+ * Send a large request to read(2)/write(2) as a smaller but still
+   reasonably large chunks, which would improve the latency when the
+   operation needs to be killed and incidentally works around broken
+   64-bit systems that cannot take a 2GB write or read in one go.
+
+ * A ".mailmap" file that ends with an incomplete line, when read
+   from a blob, was not handled properly.
+
+ * The recent "short-cut clone connectivity check" topic broke a
+   shallow repository when a fetch operation tries to auto-follow
+   tags.
+
+ * When send-email comes up with an error message to die with upon
+   failure to start an SSL session, it tried to read the error
+   string from a wrong place.
+
+ * A call to xread() was used without a loop to cope with short
+   read in the codepath to stream large blobs to a pack.
+
+ * On platforms with fgetc() and friends defined as macros, the
+   configuration parser did not compile.
+
+ * New versions of MediaWiki introduced a new API for returning
+   more than 500 results in response to a query, which would cause
+   the MediaWiki remote helper to go into an infinite loop.
+
+ * Subversion's serf access method (the only one available in
+   Subversion 1.8) for http and https URLs in skelta mode tells its
+   caller to open multiple files at a time, which made "git svn
+   fetch" complain that "Temp file with moniker 'svn_delta' already
+   in use" instead of fetching.
+
+
+Also contains a handful of trivial code clean-ups, documentation
+updates, updates to the test suite, etc.

+Git v1.8.4.2 Release Notes
+========================
+
+Fixes since v1.8.4.1
+--------------------
+
+ * "git clone" gave some progress messages to the standard output, not
+   to the standard error, and did not allow suppressing them with the
+   "--no-progress" option.
+
+ * "format-patch --from=<whom>" forgot to omit unnecessary in-body
+   from line, i.e. when <whom> is the same as the real author.
+
+ * "git shortlog" used to choke and die when there is a malformed
+   commit (e.g. missing authors); it now simply ignore such a commit
+   and keeps going.
+
+ * "git merge-recursive" did not parse its "--diff-algorithm=" command
+   line option correctly.
+
+ * "git branch --track" had a minor regression in v1.8.3.2 and later
+   that made it impossible to base your local work on anything but a
+   local branch of the upstream repository you are tracking from.
+
+ * "git ls-files -k" needs to crawl only the part of the working tree
+   that may overlap the paths in the index to find killed files, but
+   shared code with the logic to find all the untracked files, which
+   made it unnecessarily inefficient.
+
+ * When there is no sufficient overlap between old and new history
+   during a "git fetch" into a shallow repository, objects that the
+   sending side knows the receiving end has were unnecessarily sent.
+
+ * When running "fetch -q", a long silence while the sender side
+   computes the set of objects to send can be mistaken by proxies as
+   dropped connection.  The server side has been taught to send a
+   small empty messages to keep the connection alive.
+
+ * When the webserver responds with "405 Method Not Allowed", "git
+   http-backend" should tell the client what methods are allowed with
+   the "Allow" header.
+
+ * "git cvsserver" computed the permission mode bits incorrectly for
+   executable files.
+
+ * The implementation of "add -i" has a crippling code to work around
+   ActiveState Perl limitation but it by mistake also triggered on Git
+   for Windows where MSYS perl is used.
+
+ * We made sure that we notice the user-supplied GIT_DIR is actually a
+   gitfile, but did not do the same when the default ".git" is a
+   gitfile.
+
+ * When an object is not found after checking the packfiles and then
+   loose object directory, read_sha1_file() re-checks the packfiles to
+   prevent racing with a concurrent repacker; teach the same logic to
+   has_sha1_file().
+
+ * "git commit --author=$name", when $name is not in the canonical
+   "A. U. Thor <au.thor@example.xz>" format, looks for a matching name
+   from existing history, but did not consult mailmap to grab the
+   preferred author name.
+
+ * The commit object names in the insn sheet that was prepared at the
+   beginning of "rebase -i" session can become ambiguous as the
+   rebasing progresses and the repository gains more commits. Make
+   sure the internal record is kept with full 40-hex object names.
+
+ * "git rebase --preserve-merges" internally used the merge machinery
+   and as a side effect, left merge summary message in the log, but
+   when rebasing, there should not be a need for merge summary.
+
+ * "git rebase -i" forgot that the comment character can be
+   configurable while reading its insn sheet.
+
+Also contains a handful of trivial code clean-ups, documentation
+updates, updates to the test suite, etc.

+Git v1.8.4 Release Notes
+========================
+
+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics that pushes:
+
+ - only the current branch to the branch with the same name, and only
+   when the current branch is set to integrate with that remote
+   branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+   are pushing to a remote that is not where you usually fetch from.
+
+Use the user preference configuration variable "push.default" to
+change this.  If you are an old-timer who is used to the "matching"
+semantics, you can set the variable to "matching" to keep the
+traditional behaviour.  If you want to live in the future early, you
+can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands.  There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes.  A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal.  Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+
+Updates since v1.8.3
+--------------------
+
+Foreign interfaces, subsystems and ports.
+
+ * Cygwin port has been updated for more recent Cygwin 1.7.
+
+ * "git rebase -i" now honors --strategy and -X options.
+
+ * Git-gui has been updated to its 0.18.0 version.
+
+ * MediaWiki remote helper (in contrib/) has been updated to use the
+   credential helper interface from Git.pm.
+
+ * Update build for Cygwin 1.[57].  Torsten Bögershausen reports that
+   this is fine with Cygwin 1.7 ($gmane/225824) so let's try moving it
+   ahead.
+
+ * The credential helper to talk to keychain on OS X (in contrib/) has
+   been updated to kick in not just when talking http/https but also
+   imap(s) and smtp.
+
+ * Remote transport helper has been updated to report errors and
+   maintain ref hierarchy used to keep track of its own state better.
+
+ * With "export" remote-helper protocol, (1) a push that tries to
+   update a remote ref whose name is different from the pushing side
+   does not work yet, and (2) the helper may not know how to do
+   --dry-run; these problematic cases are disabled for now.
+
+ * git-remote-hg/bzr (in contrib/) updates.
+
+ * git-remote-mw (in contrib/) hints users to check the certificate,
+   when https:// connection failed.
+
+ * git-remote-mw (in contrib/) adds a command to allow previewing the
+   contents locally before pushing it out, when working with a
+   MediaWiki remote.
+
+
+UI, Workflows & Features
+
+ * Sample "post-receive-email" hook script got an enhanced replacement
+   "multimail" (in contrib/).
+
+ * Also in contrib/ is a new "contacts" script that runs "git blame"
+   to find out the people who may be interested in a set of changes.
+
+ * "git clean" command learned an interactive mode.
+
+ * The "--head" option to "git show-ref" was only to add "HEAD" to the
+   list of candidate refs to be filtered by the usual rules
+   (e.g. "--heads" that only show refs under refs/heads).  The meaning
+   of the option has been changed to always show "HEAD" regardless of
+   what filtering will be applied to any other ref.
+
+   This is a backward incompatible change and might cause breakages to
+   people's existing scripts.
+
+ * "git show -s" was less discoverable than it should have been.  It
+   now has a natural synonym "git show --no-patch".
+
+ * "git check-mailmap" is a new command that lets you map usernames
+   and e-mail addresses through the mailmap mechanism, just like many
+   built-in commands do.
+
+ * "git name-rev" learned to name an annotated tag object back to its
+   tagname; "git name-rev $(git rev-parse v1.0.0)" gives "tags/v1.0.0",
+   for example.
+
+ * "git cat-file --batch-check=<format>" is added, primarily to allow
+   on-disk footprint of objects in packfiles (often they are a lot
+   smaller than their true size, when expressed as deltas) to be
+   reported.
+
+ * "git rebase [-i]" used to leave just "rebase" as its reflog messages
+   for some operations. They have been reworded to be more informative.
+
+ * In addition to the choice from "rebase, merge, or checkout-detach",
+   "submodule update" can allow a custom command to be used in to
+   update the working tree of submodules via the "submodule.*.update"
+   configuration variable.
+
+ * "git submodule update" can optionally clone the submodule
+   repositories shallowly.
+
+ * "git format-patch" learned "--from[=whom]" option, which sets the
+   "From: " header to the specified person (or the person who runs the
+   command, if "=whom" part is missing) and move the original author
+   information to an in-body From: header as necessary.
+
+ * The configuration variable "merge.ff" was cleary a tri-state to
+   choose one from "favor fast-forward when possible", "always create
+   a merge even when the history could fast-forward" and "do not
+   create any merge, only update when the history fast-forwards", but
+   the command line parser did not implement the usual convention of
+   "last one wins, and command line overrides the configuration"
+   correctly.
+
+ * "gitweb" learned to optionally place extra links that point at the
+   levels higher than the Gitweb pages themselves in the breadcrumbs,
+   so that it can be used as part of a larger installation.
+
+ * "git log --format=" now honors i18n.logoutputencoding configuration
+   variable.
+
+ * The "push.default=simple" mode of "git push" has been updated to
+   behave like "current" without requiring a remote tracking
+   information, when you push to a remote that is different from where
+   you fetch from (i.e. a triangular workflow).
+
+ * Having multiple "fixup!" on a line in the rebase instruction sheet
+   did not work very well with "git rebase -i --autosquash".
+
+ * "git log" learned the "--author-date-order" option, with which the
+   output is topologically sorted and commits in parallel histories
+   are shown intermixed together based on the author timestamp.
+
+ * Various subcommands of "git submodule" refused to run from anywhere
+   other than the top of the working tree of the superproject, but
+   they have been taught to let you run from a subdirectory.
+
+ * "git diff" learned a mode that ignores hunks whose change consists
+   only of additions and removals of blank lines, which is the same as
+   "diff -B" (ignore blank lines) of GNU diff.
+
+ * "git rm" gives a single message followed by list of paths to report
+   multiple paths that cannot be removed.
+
+ * "git rebase" can be told with ":/look for this string" syntax commits
+   to replay the changes onto and where the work to be replayed begins.
+
+ * Many tutorials teach users to set "color.ui" to "auto" as the first
+   thing after you set "user.name/email" to introduce yourselves to
+   Git.  Now the variable defaults to "auto".
+
+ * On Cygwin, "cygstart" is now recognised as a possible way to start
+   a web browser (used in "help -w" and "instaweb" among others).
+
+ * "git status" learned status.branch and status.short configuration
+   variables to use --branch and --short options by default (override
+   with --no-branch and --no-short options from the command line).
+
+ * "git cmd <name>", when <name> happens to be a 40-hex string,
+   directly uses the 40-hex string as an object name, even if a ref
+   "refs/<some hierarchy>/<name>" exists.  This disambiguation order
+   is unlikely to change, but we should warn about the ambiguity just
+   like we warn when more than one refs/ hierarchies share the same
+   name.
+
+ * "git rebase" learned "--[no-]autostash" option to save local
+   changes instead of refusing to run (to which people's normal
+   response was to stash them and re-run).  This introduced a corner
+   case breakage to "git am --abort" but it has been fixed.
+
+ * "check-ignore" (new feature since 1.8.2) has been updated to work
+   more like "check-attr" over bidi-pipes.
+
+ * "git describe" learned "--first-parent" option to limit its closest
+   tagged commit search to the first-parent chain.
+
+ * "git merge foo" that might have meant "git merge origin/foo" is
+   diagnosed with a more informative error message.
+
+ * "git log -L<line>,<range>:<filename>" has been added.  This may
+   still have leaks and rough edges, though.
+
+ * We used the approxidate() parser for "--expire=<timestamp>" options
+   of various commands, but it is better to treat --expire=all and
+   --expire=now a bit more specially than using the current timestamp.
+   "git gc" and "git reflog" have been updated with a new parsing
+   function for expiry dates.
+
+ * Updates to completion (both bash and zsh) helpers.
+
+ * The behaviour of the "--chain-reply-to" option of "git send-email"
+   have changed at 1.7.0, and we added a warning/advice message to
+   help users adjust to the new behaviour back then, but we kept it
+   around for too long.  The message has finally been removed.
+
+ * "git fetch origin master" unlike "git fetch origin" or "git fetch"
+   did not update "refs/remotes/origin/master"; this was an early
+   design decision to keep the update of remote tracking branches
+   predictable, but in practice it turns out that people find it more
+   convenient to opportunistically update them whenever we have a
+   chance, and we have been updating them when we run "git push" which
+   already breaks the original "predictability" anyway.
+
+ * The configuration variable core.checkstat was advertised in the
+   documentation but the code expected core.statinfo instead.
+   For now, we accept both core.checkstat and core.statinfo, but the
+   latter will be removed in the longer term.
+
+
+Performance, Internal Implementation, etc.
+
+ * On Cygwin, we used to use our own lstat(2) emulation that is
+   allegedly faster than the platform one in codepaths where some of
+   the information it returns did not matter, but it started to bite
+   us in a few codepaths where the trick it uses to cheat does show
+   breakages. This emulation has been removed and we use the native
+   lstat(2) emulation supplied by Cygwin now.
+
+ * The function attributes extensions are used to catch mistakes in
+   use of our own variadic functions that use NULL sentinel at the end
+   (i.e. like execl(3)) and format strings (i.e. like printf(3)).
+
+ * The code to allow configuration data to be read from in-tree blob
+   objects is in.  This may help working in a bare repository and
+   submodule updates.
+
+ * Fetching between repositories with many refs employed O(n^2)
+   algorithm to match up the common objects, which has been corrected.
+
+ * The original way to specify remote repository using .git/branches/
+   used to have a nifty feature.  The code to support the feature was
+   still in a function but the caller was changed not to call it 5
+   years ago, breaking that feature and leaving the supporting code
+   unreachable.  The dead code has been removed.
+
+ * "git pack-refs" that races with new ref creation or deletion have
+   been susceptible to lossage of refs under right conditions, which
+   has been tightened up.
+
+ * We read loose and packed references in two steps, but after
+   deciding to read a loose ref but before actually opening it to read
+   it, another process racing with us can unlink it, which would cause
+   us to barf.  The codepath has been updated to retry when such a
+   race is detected, instead of outright failing.
+
+ * Uses of the platform fnmatch(3) function (many places in the code,
+   matching pathspec, .gitignore and .gitattributes to name a few)
+   have been replaced with wildmatch, allowing "foo/**/bar" that would
+   match foo/bar, foo/a/bar, foo/a/b/bar, etc.
+
+ * Memory ownership and lifetime rules for what for-each-ref feeds to
+   its callbacks have been clarified (in short, "you do not own it, so
+   make a copy if you want to keep it").
+
+ * The revision traversal logic to improve culling of irrelevant
+   parents while traversing a mergy history has been updated.
+
+ * Some leaks in unpack-trees (used in merge, cherry-pick and other
+   codepaths) have been plugged.
+
+ * The codepath to read from marks files in fast-import/export did not
+   have to accept anything but 40-hex representation of the object
+   name.  Further, fast-export did not need full in-core object
+   representation to have parsed wen reading from them.  These
+   codepaths have been optimized by taking advantage of these access
+   patterns.
+
+ * Object lookup logic, when the object hashtable starts to become
+   crowded, has been optimized.
+
+ * When TEST_OUTPUT_DIRECTORY setting is used, it was handled somewhat
+   inconsistently between the test framework and t/Makefile, and logic
+   to summarize the results looked at a wrong place.
+
+ * "git clone" uses a lighter-weight implementation when making sure
+   that the history behind refs are complete.
+
+ * Many warnings from sparse source checker in compat/ area has been
+   squelched.
+
+ * The code to reading and updating packed-refs file has been updated,
+   correcting corner case bugs.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.3
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.3 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * Newer Net::SMTP::SSL module does not want the user programs to use
+   the default behaviour to let server certificate go without
+   verification, so by default enable the verification with a
+   mechanism to turn it off if needed.
+   (merge 35035bb rr/send-email-ssl-verify later to maint).
+
+ * When "git" is spawned in such a way that any of the low 3 file
+   descriptors is closed, our first open() may yield file descriptor 2,
+   and writing error message to it would screw things up in a big way.
+   (merge a11c396 tr/protect-low-3-fds later to maint).
+
+ * The mailmap mechanism unnecessarily downcased the e-mail addresses
+   in the output, and also ignored the human name when it is a single
+   character name.
+   (merge bd23794 jc/mailmap-case-insensitivity later to maint).
+
+ * In two places we did not check return value (expected to be a file
+   descriptor) correctly.
+   (merge a77f106 tr/fd-gotcha-fixes later to maint).
+
+ * Logic to auto-detect character encodings in the commit log message
+   did not reject overlong and invalid UTF-8 characters.
+   (merge 81050ac bc/commit-invalid-utf8 later to maint).
+
+ * Pass port number as a separate argument when "send-email" initializes
+   Net::SMTP, instead of as a part of the hostname, i.e. host:port.
+   This allows GSSAPI codepath to match with the hostname given.
+   (merge 1a741bf bc/send-email-use-port-as-separate-param later to maint).
+
+ * "git diff" refused to even show difference when core.safecrlf is
+   set to true (i.e. error out) and there are offending lines in the
+   working tree files.
+   (merge 5430bb2 jc/maint-diff-core-safecrlf later to maint).
+
+ * A test that should have failed but didn't revealed a bug that needs
+   to be corrected.
+   (merge 94d75d1 jc/t1512-fix later to maint).
+
+ * An overlong path to a .git directory may have overflown the
+   temporary path buffer used to create a name for lockfiles.
+   (merge 2fbd4f9 mh/maint-lockfile-overflow later to maint).
+
+ * Invocations of "git checkout" used internally by "git rebase" were
+   counted as "checkout", and affected later "git checkout -" to the
+   the user to an unexpected place.
+   (merge 3bed291 rr/rebase-checkout-reflog later to maint).
+
+ * The configuration variable column.ui was poorly documented.
+   (merge 5e62cc1 rr/column-doc later to maint).
+
+ * "git name-rev --refs=tags/v*" were forbidden, which was a bit
+   inconvenient (you had to give a pattern to match refs fully, like
+   --refs=refs/tags/v*).
+   (merge 98c5c4a nk/name-rev-abbreviated-refs later to maint).
+
+ * "git apply" parsed patches that add new files, generated by
+   programs other than Git, incorrectly.  This is an old breakage in
+   v1.7.11 and will need to be merged down to the maintenance tracks.
+
+ * Older cURL wanted piece of memory we call it with to be stable, but
+   we updated the auth material after handing it to a call.
+
+ * "git pull" into nothing trashed "local changes" that were in the
+   index, and this avoids it.
+
+ * Many "git submodule" operations do not work on a submodule at a
+   path whose name is not in ASCII.
+
+ * "cherry-pick" had a small leak in an error codepath.
+
+ * Logic used by git-send-email to suppress cc mishandled names like
+   "A U. Thor" <author@example.xz>, where the human readable part
+   needs to be quoted (the user input may not have the double quotes
+   around the name, and comparison was done between quoted and
+   unquoted strings).  It also mishandled names that need RFC2047
+   quoting.
+
+ * Call to discard_cache/discard_index (used when we use different
+   contents of the index in-core, in many operations like commit,
+   apply, and merge) used to leak memory that held the array of index
+   entries, which has been plugged.
+   (merge a0fc4db rs/discard-index-discard-array later to maint).
+
+ * "gitweb" forgot to clear a global variable $search_regexp upon each
+   request, mistakenly carrying over the previous search to a new one
+   when used as a persistent CGI.
+
+ * The wildmatch engine did not honor WM_CASEFOLD option correctly.
+
+ * "git log -c --follow $path" segfaulted upon hitting the commit that
+   renamed the $path being followed.
+
+ * When a reflog notation is used for implicit "current branch", we
+   did not say which branch and worse said "branch ''".
+
+ * "difftool --dir-diff" did not copy back changes made by the
+   end-user in the diff tool backend to the working tree in some
+   cases.
+
+ * "git push $there HEAD:branch" did not resolve HEAD early enough, so
+   it was easy to flip it around while push is still going on and push
+   out a branch that the user did not originally intended when the
+   command was started.
+
+ * The bash prompt code (in contrib/) displayed the name of the branch
+   being rebased when "rebase -i/-m/-p" modes are in use, but not the
+   plain vanilla "rebase".
+
+ * Handling of negative exclude pattern for directories "!dir" was
+   broken in the update to v1.8.3.
+
+ * zsh prompt script that borrowed from bash prompt script did not
+   work due to slight differences in array variable notation between
+   these two shells.
+
+ * An entry for "file://" scheme in the enumeration of URL types Git
+   can take in the HTML documentation was made into a clickable link
+   by mistake.
+
+ * "git push --[no-]verify" was not documented.
+
+ * Stop installing the git-remote-testpy script that is only used for
+   testing.
+
+ * "git commit --allow-empty-message -m ''" should not start an
+   editor.
+
+ * "git merge @{-1}~22" was rewritten to "git merge frotz@{1}~22"
+   incorrectly when your previous branch was "frotz" (it should be
+   rewritten to "git merge frotz~22" instead).
+
+ * "git diff -c -p" was not showing a deleted line from a hunk when
+   another hunk immediately begins where the earlier one ends.
+
+ * "git log --ancestry-path A...B" did not work as expected, as it did
+   not pay attention to the fact that the merge base between A and B
+   was the bottom of the range being specified.
+
+ * Mac OS X does not like to write(2) more than INT_MAX number of
+   bytes; work it around by chopping write(2) into smaller pieces.
+
+ * Newer MacOS X encourages the programs to compile and link with
+   their CommonCrypto, not with OpenSSL.
+
+ * "git clone foo/bar:baz" cannot be a request to clone from a remote
+   over git-over-ssh specified in the scp style.  This case is now
+   detected and clones from a local repository at "foo/bar:baz".
+
+ * When $HOME is misconfigured to point at an unreadable directory, we
+   used to complain and die. Loosen the check.
+
+ * "git subtree" (in contrib/) had one codepath with loose error
+   checks to lose data at the remote side.
+
+ * "git fetch" into a shallow repository from a repository that does
+   not know about the shallow boundary commits (e.g. a different fork
+   from the repository the current shallow repository was cloned from)
+   did not work correctly.
+
+ * "git checkout foo" DWIMs the intended "upstream" and turns it into
+   "git checkout -t -b foo remotes/origin/foo". This codepath has been
+   updated to correctly take existing remote definitions into account.

-Checklist (and a short version for the impatient):
-
-	Commits:
-
-	- make commits of logical units
-	- check for unnecessary whitespace with "git diff --check"
-	  before committing
-	- do not check in commented out code or unneeded files
-	- the first line of the commit message should be a short
-	  description (50 characters is the soft limit, see DISCUSSION
-	  in git-commit(1)), and should skip the full stop
-	- it is also conventional in most cases to prefix the
-	  first line with "area: " where the area is a filename
-	  or identifier for the general area of the code being
-	  modified, e.g.
-	  . archive: ustar header checksum is computed unsigned
-	  . git-cherry-pick.txt: clarify the use of revision range notation
-	  (if in doubt which identifier to use, run "git log --no-merges"
-	  on the files you are modifying to see the current conventions)
-	- the body should provide a meaningful commit message, which:
-	  . explains the problem the change tries to solve, iow, what
-	    is wrong with the current code without the change.
-	  . justifies the way the change solves the problem, iow, why
-	    the result with the change is better.
-	  . alternate solutions considered but discarded, if any.
-	- describe changes in imperative mood, e.g. "make xyzzy do frotz"
-	  instead of "[This patch] makes xyzzy do frotz" or "[I] changed
-	  xyzzy to do frotz", as if you are giving orders to the codebase
-	  to change its behaviour.
-	- try to make sure your explanation can be understood without
-	  external resources. Instead of giving a URL to a mailing list
-	  archive, summarize the relevant points of the discussion.
-	- add a "Signed-off-by: Your Name <you@example.com>" line to the
-	  commit message (or just use the option "-s" when committing)
-	  to confirm that you agree to the Developer's Certificate of Origin
-	- make sure that you have tests for the bug you are fixing
-	- make sure that the test suite passes after your commit
-
-	Patch:
-
-	- use "git format-patch -M" to create the patch
-	- do not PGP sign your patch
-	- do not attach your patch, but read in the mail
-	  body, unless you cannot teach your mailer to
-	  leave the formatting of the patch alone.
-	- be careful doing cut & paste into your mailer, not to
-	  corrupt whitespaces.
-	- provide additional information (which is unsuitable for
-	  the commit message) between the "---" and the diffstat
-	- if you change, add, or remove a command line option or
-	  make some other user interface change, the associated
-	  documentation should be updated as well.
-	- if your name is not writable in ASCII, make sure that
-	  you send off a message in the correct encoding.
-	- send the patch to the list (git@vger.kernel.org) and the

+(2) Describe your changes well.
+
+The first line of the commit message should be a short description (50
+characters is the soft limit, see DISCUSSION in git-commit(1)), and
+should skip the full stop.  It is also conventional in most cases to
+prefix the first line with "area: " where the area is a filename or
+identifier for the general area of the code being modified, e.g.
+
+  . archive: ustar header checksum is computed unsigned
+  . git-cherry-pick.txt: clarify the use of revision range notation
+
+If in doubt which identifier to use, run "git log --no-merges" on the
+files you are modifying to see the current conventions.
+
+The body should provide a meaningful commit message, which:
 
-git based diff tools generate unidiff which is the preferred format.
+  . explains the problem the change tries to solve, iow, what is wrong
+    with the current code without the change.
+
+  . justifies the way the change solves the problem, iow, why the
+    result with the change is better.
+
+  . alternate solutions considered but discarded, if any.
+
+Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
+instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
+to do frotz", as if you are giving orders to the codebase to change
+its behaviour.  Try to make sure your explanation can be understood

+	This variable can be used to set both `receive.hiderefs`
+	and `uploadpack.hiderefs` at the same time to the same

 transfer.unpackLimit::
 	When `fetch.unpackLimit` or `receive.unpackLimit` are
 	not set, the value of this variable is used instead.
 	The default value is 100.
 
+uploadpack.hiderefs::
+	String(s) `upload-pack` uses to decide which refs to omit
+	from its initial advertisement.  Use more than one
+	definitions to specify multiple prefix strings. A ref that
+	are under the hierarchies listed on the value of this
+	variable is excluded, and is hidden from `git ls-remote`,
+	`git fetch`, etc.  An attempt to fetch a hidden ref by `git
+	fetch` will fail.  See also `uploadpack.allowtipsha1inwant`.
+
+uploadpack.allowtipsha1inwant::
+	When `uploadpack.hiderefs` is in effect, allow `upload-pack`
+	to accept a fetch request that asks for an object at the tip
+	of a hidden ref (by default, such a request is rejected).
+	see also `uploadpack.hiderefs`.
+
+uploadpack.keepalive::
+	When `upload-pack` has started `pack-objects`, there may be a
+	quiet period while `pack-objects` prepares the pack. Normally
+	it would output progress information, but if `--quiet` was used
+	for the fetch, `pack-objects` will output nothing at all until
+	the pack data begins. Some clients and networks may consider
+	the server to be hung and give up. Setting this option instructs
+	`upload-pack` to send an empty keepalive packet every
+	`uploadpack.keepalive` seconds. Setting this option to 0
+	disables keepalive packets entirely. The default is 5 seconds.

 	Any URL that starts with this value will be rewritten to

+BATCH OUTPUT
+------------
+
+If `--batch` or `--batch-check` is given, `cat-file` will read objects
+from stdin, one per line, and print information about them.
+
+Each line is considered as a whole object name, and is parsed as if
+given to linkgit:git-rev-parse[1].
+
+You can specify the information shown for each object by using a custom
+`<format>`. The `<format>` is copied literally to stdout for each
+object, with placeholders of the form `%(atom)` expanded, followed by a
+newline. The available atoms are:
+
+`objectname`::
+	The 40-hex object name of the object.
+
+`objecttype`::
+	The type of of the object (the same as `cat-file -t` reports).
+
+`objectsize`::
+	The size, in bytes, of the object (the same as `cat-file -s`
+	reports).
+
+`objectsize:disk`::
+	The size, in bytes, that the object takes up on disk. See the
+	note about on-disk sizes in the `CAVEATS` section below.
+
+If no format is specified, the default format is `%(objectname)
+%(objecttype) %(objectsize)`.
+
+If `--batch` is specified, the object information is followed by the
+object contents (consisting of `%(objectsize)` bytes), followed by a
+newline.
+
+For example, `--batch` without a custom format would produce:
 
 ------------
 <sha1> SP <type> SP <size> LF
 <contents> LF
 ------------
 
-If '--batch-check' is specified, output of the following form is printed for

+Whereas `--batch-check='%(objectname) %(objecttype)'` would produce:

-For both '--batch' and '--batch-check', output of the following form is printed

+
+CAVEATS
+-------
+
+Note that the sizes of objects on disk are reported accurately, but care
+should be taken in drawing conclusions about which refs or objects are
+responsible for disk usage. The size of a packed non-delta object may be
+much larger than the size of objects which delta against it, but the
+choice of which object is the base and which is the delta is arbitrary
+and is subject to change during a repack. Note also that multiple copies
+of an object may be present in the object database; in this case, it is
+undefined which copy's size will be reported.

+===================
+
+NAME
+----
+git-check-ignore - Debug gitignore / exclude files
+
+
+SYNOPSIS
+--------
+[verse]
+'git check-ignore' [options] pathname...
+'git check-ignore' [options] --stdin < <list-of-paths>
+
+DESCRIPTION
+-----------
+
+For each pathname given via the command-line or from a file via
+`--stdin`, show the pattern from .gitignore (or other input files to
+the exclude mechanism) that decides if the pathname is excluded or
+included.  Later patterns within a file take precedence over earlier
+ones.
+
+OPTIONS
+-------
+-q, --quiet::
+	Don't output anything, just set exit status.  This is only
+	valid with a single pathname.
+
+-v, --verbose::
+	Also output details about the matching pattern (if any)
+	for each given pathname.
+
+--stdin::
+	Read file names from stdin instead of from the command-line.
+
+-z::
+	The output format is modified to be machine-parseable (see
+	below).  If `--stdin` is also given, input paths are separated
+	with a NUL character instead of a linefeed character.
+
+-n, --non-matching::
+	Show given paths which don't match any pattern.	 This only
+	makes sense when `--verbose` is enabled, otherwise it would
+	not be possible to distinguish between paths which match a
+	pattern and those which don't.
+
+OUTPUT
+------
+
+By default, any of the given pathnames which match an ignore pattern
+will be output, one per line.  If no pattern matches a given path,
+nothing will be output for that path; this means that path will not be
+ignored.
+
+If `--verbose` is specified, the output is a series of lines of the form:
+
+<source> <COLON> <linenum> <COLON> <pattern> <HT> <pathname>
+
+<pathname> is the path of a file being queried, <pattern> is the
+matching pattern, <source> is the pattern's source file, and <linenum>
+is the line number of the pattern within that source.  If the pattern
+contained a `!` prefix or `/` suffix, it will be preserved in the
+output.  <source> will be an absolute path when referring to the file
+configured by `core.excludesfile`, or relative to the repository root
+when referring to `.git/info/exclude` or a per-directory exclude file.
+
+If `-z` is specified, the pathnames in the output are delimited by the
+null character; if `--verbose` is also specified then null characters
+are also used instead of colons and hard tabs:
+
+<source> <NULL> <linenum> <NULL> <pattern> <NULL> <pathname> <NULL>
+
+If `-n` or `--non-matching` are specified, non-matching pathnames will
+also be output, in which case all fields in each output record except
+for <pathname> will be empty.  This can be useful when running
+non-interactively, so that files can be incrementally streamed to
+STDIN of a long-running check-ignore process, and for each of these
+files, STDOUT will indicate whether that file matched a pattern or
+not.  (Without this option, it would be impossible to tell whether the
+absence of output for a given file meant that it didn't match any
+pattern, or that the output hadn't been generated yet.)
+
+Buffering happens as documented under the `GIT_FLUSH` option in
+linkgit:git[1].  The caller is responsible for avoiding deadlocks
+caused by overfilling an input buffer or reading from an empty output
+buffer.
+
+EXIT STATUS

+Interactive mode
+----------------
+When the command enters the interactive mode, it shows the
+files and directories to be cleaned, and goes into its
+interactive command loop.
+
+The command loop shows the list of subcommands available, and
+gives a prompt "What now> ".  In general, when the prompt ends
+with a single '>', you can pick only one of the choices given
+and type return, like this:
+
+------------
+    *** Commands ***
+	1: clean                2: filter by pattern    3: select by numbers
+	4: ask each             5: quit                 6: help
+    What now> 1

+
+You also could say `c` or `clean` above as long as the choice is unique.
+
+The main command loop has 6 subcommands.
+
+clean::
+
+   Start cleaning files and directories, and then quit.
+
+filter by pattern::
+
+   This shows the files and directories to be deleted and issues an
+   "Input ignore patterns>>" prompt. You can input space-seperated
+   patterns to exclude files and directories from deletion.
+   E.g. "*.c *.h" will excludes files end with ".c" and ".h" from
+   deletion. When you are satisfied with the filtered result, press
+   ENTER (empty) back to the main menu.
+
+select by numbers::
+
+   This shows the files and directories to be deleted and issues an
+   "Select items to delete>>" prompt. When the prompt ends with double
+   '>>' like this, you can make more than one selection, concatenated
+   with whitespace or comma.  Also you can say ranges.  E.g. "2-5 7,9"
+   to choose 2,3,4,5,7,9 from the list.  If the second number in a
+   range is omitted, all remaining items are selected.  E.g. "7-" to

 All the operations required for normal use are supported, including
 checkout, diff, status, update, log, add, remove, commit.
+
+Most CVS command arguments that read CVS tags or revision numbers
+(typically -r) work, and also support any git refspec
+(tag, branch, commit ID, etc).
+However, CVS revision numbers for non-default branches are not well
+emulated, and cvs log does not show tags or branches at
+all.  (Non-main-branch CVS revision numbers superficially resemble CVS
+revision numbers, but they actually encode a git commit ID directly,
+rather than represent the number of revisions since the branch point.)
+
+Note that there are two ways to checkout a particular branch.
+As described elsewhere on this page, the "module" parameter
+of cvs checkout is interpreted as a branch name, and it becomes
+the main branch.  It remains the main branch for a given sandbox
+even if you temporarily make another branch sticky with
+cvs update -r.  Alternatively, the -r argument can indicate
+some other branch to actually checkout, even though the module
+is still the "main" branch.  Tradeoffs (as currently
+implemented): Each new "module" creates a new database on disk with
+a history for the given module, and after the database is created,
+operations against that main branch are fast.  Or alternatively,
+-r doesn't take any extra disk space, but may be significantly slower for
+many operations, like cvs update.
+
+If you want to refer to a git refspec that has characters that are
+not allowed by CVS, you have two options.  First, it may just work
+to supply the git refspec directly to the appropriate CVS -r argument;
+some CVS clients don't seem to do much sanity checking of the argument.
+Second, if that fails, you can use a special character escape mechanism
+that only uses characters that are valid in CVS tags.  A sequence
+of 4 or 5 characters of the form (underscore (`"_"`), dash (`"-"`),
+one or two characters, and dash (`"-"`)) can encode various characters based
+on the one or two letters: `"s"` for slash (`"/"`), `"p"` for
+period (`"."`), `"u"` for underscore (`"_"`), or two hexadecimal digits
+for any byte value at all (typically an ASCII number, or perhaps a part
+of a UTF-8 encoded character).
+
 Legacy monitoring operations are not supported (edit, watch and related).
 Exports and tagging (tags and branches) are not supported at this stage.

+MERGING TAG
+-----------
+
+When merging an annotated (and possibly signed) tag, Git always
+creates a merge commit even if a fast-forward merge is possible, and
+the commit message template is prepared with the tag message.
+Additionally, if the tag is signed, the signature check is reported
+as a comment in the message template. See also linkgit:git-tag[1].
+
+When you want to just integrate with the work leading to the commit
+that happens to be tagged, e.g. synchronizing with an upstream
+release point, you may not want to make an unnecessary merge commit.
+
+In such a case, you can "unwrap" the tag yourself before feeding it
+to `git merge`, or pass `--ff-only` when you do not have any work on
+your own. e.g.
+
+----
+git fetch origin

+Submodules
+~~~~~~~~~~
+Only submodules using a gitfile (which means they were cloned
+with a Git version 1.7.8 or newer) will be removed from the work
+tree, as their repository lives inside the .git directory of the
+superproject. If a submodule (or one of those nested inside it)
+still uses a .git directory, `git rm` will fail - no matter if forced
+or not - to protect the submodule's history.
+
+A submodule is considered up-to-date when the HEAD is the same as
+recorded in the index, no tracked files are modified and no untracked
+files that aren't ignored are present in the submodules work tree.
+Ignored files are deemed expendable and won't stop a submodule's work
+tree from being removed.

 SYNOPSIS
 --------
 [verse]
-'git shell' [-c <command> <argument>]
+'chsh' -s $(command -v git-shell) <user>
+'git clone' <user>`@localhost:/path/to/repo.git`
+'ssh' <user>`@localhost`
 
 DESCRIPTION
 -----------
 
-A login shell for SSH accounts to provide restricted Git access. When
-'-c' is given, the program executes <command> non-interactively;
-<command> can be one of 'git receive-pack', 'git upload-pack', 'git
-upload-archive', 'cvs server', or a command in COMMAND_DIR. The shell
-is started in interactive mode when no arguments are given; in this
-case, COMMAND_DIR must exist, and any of the executables in it can be
-invoked.
+This is a login shell for SSH accounts to provide restricted Git access.
+It permits execution only of server-side Git commands implementing the
+pull/push functionality, plus custom commands present in a subdirectory
+named `git-shell-commands` in the user's home directory.
 
-'cvs server' is a special command which executes git-cvsserver.
+COMMANDS
+--------
+
+'git shell' accepts the following commands after the '-c' option:
+
+'git receive-pack <argument>'::
+'git upload-pack <argument>'::
+'git upload-archive <argument>'::
+	Call the corresponding server-side command to support
+	the client's 'git push', 'git fetch', or 'git archive --remote'
+	request.
+'cvs server'::
+	Imitate a CVS server.  See linkgit:git-cvsserver[1].
+
+If a `~/git-shell-commands` directory is present, 'git shell' will
+also handle other, custom commands by running
+"`git-shell-commands/<command> <arguments>`" from the user's home
+directory.
+
+INTERACTIVE USE
+---------------
+
+By default, the commands above can be executed only with the '-c'
+option; the shell is not interactive.
 
-COMMAND_DIR is the path "$HOME/git-shell-commands". The user must have
-read and execute permissions to the directory in order to execute the
-programs in it. The programs are executed with a cwd of $HOME, and
-<argument> is parsed as a command-line string.
+If a `~/git-shell-commands` directory is present, 'git shell'
+can also be run interactively (with no arguments).  If a `help`
+command is present in the `git-shell-commands` directory, it is
+run to provide the user with an overview of allowed actions.  Then a
+"git> " prompt is presented at which one can enter any of the
+commands from the `git-shell-commands` directory, or `exit` to close
+the connection.
+
+Generally this mode is used as an administrative interface to allow
+users to list repositories they have access to, create, delete, or
+rename repositories, or change repository descriptions and
+permissions.
+
+If a `no-interactive-login` command exists, then it is run and the
+interactive shell is aborted.
+
+EXAMPLE
+-------
+
+To disable interactive logins, displaying a greeting instead:
++
+----------------
+$ chsh -s /usr/bin/git-shell
+$ mkdir $HOME/git-shell-commands
+$ cat >$HOME/git-shell-commands/no-interactive-login <<\EOF
+#!/bin/sh
+printf '%s\n' "Hi $USER! You've successfully authenticated, but I do not"
+printf '%s\n' "provide interactive shell access."
+exit 128

+$ chmod +x $HOME/git-shell-commands/no-interactive-login

+
+   At this point, build-test the result.  It may reveal semantic

+Appendix
+--------
+
+Preparing a "merge-fix"
+~~~~~~~~~~~~~~~~~~~~~~~
+
+A merge of two topics may not textually conflict but still have
+conflict at the semantic level. A classic example is for one topic
+to rename an variable and all its uses, while another topic adds a
+new use of the variable under its old name. When these two topics
+are merged together, the reference to the variable newly added by
+the latter topic will still use the old name in the result.
+
+The Meta/Reintegrate script that is used by redo-jch and redo-pu
+scripts implements a crude but usable way to work this issue around.
+When the script merges branch $X, it checks if "refs/merge-fix/$X"
+exists, and if so, the effect of it is squashed into the result of
+the mechanical merge.  In other words,
+
+     $ echo $X | Meta/Reintegrate
+
+is roughly equivalent to this sequence:
+
+     $ git merge --rerere-autoupdate $X
+     $ git commit
+     $ git cherry-pick -n refs/merge-fix/$X
+     $ git commit --amend
+
+The goal of this "prepare a merge-fix" step is to come up with a
+commit that can be squashed into a result of mechanical merge to
+correct semantic conflicts.
+
+After finding that the result of merging branch "ai/topic" to an
+integration branch had such a semantic conflict, say pu~4, check the
+problematic merge out on a detached HEAD, edit the working tree to
+fix the semantic conflict, and make a separate commit to record the
+fix-up:
+
+     $ git checkout pu~4
+     $ git show -s --pretty=%s ;# double check
+     Merge branch 'ai/topic' to pu
+     $ edit
+     $ git commit -m 'merge-fix/ai/topic' -a
+
+Then make a reference "refs/merge-fix/ai/topic" to point at this
+result:
+
+     $ git update-ref refs/merge-fix/ai/topic HEAD
+
+Then double check the result by asking Meta/Reintegrate to redo the
+merge:
+
+     $ git checkout pu~5 ;# the parent of the problem merge
+     $ echo ai/topic | Meta/Reintegrate
+     $ git diff pu~4
+
+This time, because you prepared refs/merge-fix/ai/topic, the
+resulting merge should have been tweaked to include the fix for the
+semantic conflict.
+
+Note that this assumes that the order in which conflicting branches
+are merged does not change.  If the reason why merging ai/topic
+branch needs this merge-fix is because another branch merged earlier
+to the integration branch changed the underlying assumption ai/topic
+branch made (e.g. ai/topic branch added a site to refer to a
+variable, while the other branch renamed that variable and adjusted
+existing use sites), and if you changed redo-jch (or redo-pu) script
+to merge ai/topic branch before the other branch, then the above
+merge-fix should not be applied while merging ai/topic, but should
+instead be applied while merging the other branch.  You would need
+to move the fix to apply to the other branch, perhaps like this:
+
+      $ mf=refs/merge-fix
+      $ git update-ref $mf/$the_other_branch $mf/ai/topic
+      $ git update-ref -d $mf/ai/topic

+
+How to integrate new subcommands
+================================
+
+This is how-to documentation for people who want to add extension
+commands to Git.  It should be read alongside api-builtin.txt.
+
+Runtime environment
+-------------------
+
+Git subcommands are standalone executables that live in the Git exec
+path, normally /usr/lib/git-core.  The git executable itself is a
+thin wrapper that knows where the subcommands live, and runs them by
+passing command-line arguments to them.
+
+(If "git foo" is not found in the Git exec path, the wrapper
+will look in the rest of your $PATH for it.  Thus, it's possible
+to write local Git extensions that don't live in system space.)
+
+Implementation languages
+------------------------
+
+Most subcommands are written in C or shell.  A few are written in
+Perl.
+
+While we strongly encourage coding in portable C for portability,
+these specific scripting languages are also acceptable.  We won't
+accept more without a very strong technical case, as we don't want
+to broaden the Git suite's required dependencies.  Import utilities,
+surgical tools, remote helpers and other code at the edges of the
+Git suite are more lenient and we allow Python (and even Tcl/tk),
+but they should not be used for core functions.
+
+This may change in the future.  Especially Python is not allowed in
+core because we need better Python integration in the Git Windows
+installer before we can be confident people in that environment
+won't experience an unacceptably large loss of capability.
+
+C commands are normally written as single modules, named after the
+command, that link a collection of functions called libgit.  Thus,
+your command 'git-foo' would normally be implemented as a single
+"git-foo.c" (or "builtin/foo.c" if it is to be linked to the main
+binary); this organization makes it easy for people reading the code
+to find things.
+
+See the CodingGuidelines document for other guidance on what we consider
+good practice in C and shell, and api-builtin.txt for the support
+functions available to built-in commands written in C.
+
+What every extension command needs
+----------------------------------
+
+You must have a man page, written in asciidoc (this is what Git help
+followed by your subcommand name will display).  Be aware that there is
+a local asciidoc configuration and macros which you should use.  It's
+often helpful to start by cloning an existing page and replacing the
+text content.
+
+You must have a test, written to report in TAP (Test Anything Protocol).
+Tests are executables (usually shell scripts) that live in the 't'
+subdirectory of the tree.  Each test name begins with 't' and a sequence
+number that controls where in the test sequence it will be executed;
+conventionally the rest of the name stem is that of the command
+being tested.
+
+Read the file t/README to learn more about the conventions to be used
+in writing tests, and the test support library.
+
+Integrating a command
+---------------------
+
+Here are the things you need to do when you want to merge a new
+subcommand into the Git tree.
+
+1. Don't forget to sign off your patch!
+
+2. Append your command name to one of the variables BUILTIN_OBJS,
+EXTRA_PROGRAMS, SCRIPT_SH, SCRIPT_PERL or SCRIPT_PYTHON.
+
+3. Drop its test in the t directory.
+
+4. If your command is implemented in an interpreted language with a
+p-code intermediate form, make sure .gitignore in the main directory
+includes a pattern entry that ignores such files.  Python .pyc and
+.pyo files will already be covered.
+
+5. If your command has any dependency on a particular version of
+your language, document it in the INSTALL file.
+
+6. There is a file command-list.txt in the distribution main directory
+that categorizes commands by type, so they can be listed in appropriate
+subsections in the documentation's summary command list.  Add an entry
+for yours.  To understand the categories, look at git-commands.txt
+in the main directory.
+
+7. Give the maintainer one paragraph to include in the RelNotes file
+to describe the new feature; a good place to do so is in the cover
+letter [PATCH 0/n].
+
+That's all there is to it.

-NOME
-----
-gittutorial - Um tutorial de introdução ao git (para versão 1.5.1 ou mais nova)
-
-SINOPSE
---------
-git *
-
-DESCRIÇÃO
------------
-
-Este tutorial explica como importar um novo projeto para o git,
-adicionar mudanças a ele, e compartilhar mudanças com outros
-desenvolvedores.
-
-Se, ao invés disso, você está interessado primariamente em usar git para
-obter um projeto, por exemplo, para testar a última versão, você pode
-preferir começar com os primeiros dois capítulos de
-link:user-manual.html[O Manual do Usuário Git].
-
-Primeiro, note que você pode obter documentação para um comando como
-`git log --graph` com:
-
-------------------------------------------------
-$ man git-log
-------------------------------------------------
-
-ou:
-
-------------------------------------------------
-$ git help log
-------------------------------------------------
-
-Com a última forma, você pode usar o visualizador de manual de sua
-escolha; veja linkgit:git-help[1] para maior informação.
-
-É uma boa idéia informar ao git seu nome e endereço público de email
-antes de fazer qualquer operação. A maneira mais fácil de fazê-lo é:
-
-------------------------------------------------
-$ git config --global user.name "Seu Nome Vem Aqui"
-$ git config --global user.email voce@seudominio.exemplo.com
-------------------------------------------------
-
-
-Importando um novo projeto
------------------------
-
-Assuma que você tem um tarball project.tar.gz com seu trabalho inicial.
-Você pode colocá-lo sob controle de revisão git da seguinte forma:
-
-------------------------------------------------
-$ tar xzf project.tar.gz
-$ cd project
-$ git init
-------------------------------------------------
-
-Git irá responder
-
-------------------------------------------------
-Initialized empty Git repository in .git/
-------------------------------------------------
-
-Agora que você iniciou seu diretório de trabalho, você deve ter notado que um
-novo diretório foi criado com o nome de ".git".
-
-A seguir, diga ao git para gravar um instantâneo do conteúdo de todos os
-arquivos sob o diretório atual (note o '.'), com 'git-add':
-
-------------------------------------------------
-$ git add .
-------------------------------------------------
-
-Este instantâneo está agora armazenado em uma área temporária que o git
-chama de "index" ou índice. Você pode armazenar permanentemente o
-conteúdo do índice no repositório com 'git-commit':
-
-------------------------------------------------
-$ git commit
-------------------------------------------------
-
-Isto vai te pedir por uma mensagem de commit. Você agora gravou sua
-primeira versão de seu projeto no git.
-
-Fazendo mudanças
---------------
-
-Modifique alguns arquivos, e, então, adicione seu conteúdo atualizado ao
-índice:
-
-------------------------------------------------
-$ git add file1 file2 file3
-------------------------------------------------
-
-Você está agora pronto para fazer o commit. Você pode ver o que está
-para ser gravado usando 'git-diff' com a opção --cached:
-
-------------------------------------------------
-$ git diff --cached
-------------------------------------------------
-
-(Sem --cached, o comando 'git-diff' irá te mostrar quaisquer mudanças
-que você tenha feito mas ainda não adicionou ao índice.) Você também
-pode obter um breve sumário da situação com 'git-status':
-
-------------------------------------------------
-$ git status
-# On branch master
-# Changes to be committed:
-#   (use "git reset HEAD <file>..." to unstage)
-#
-#	modified:   file1
-#	modified:   file2
-#	modified:   file3
-#
-------------------------------------------------
-
-Se você precisar fazer qualquer outro ajuste, faça-o agora, e, então,
-adicione qualquer conteúdo modificado ao índice. Finalmente, grave suas
-mudanças com:
-
-------------------------------------------------
-$ git commit
-------------------------------------------------
-
-Ao executar esse comando, ele irá te pedir uma mensagem descrevendo a mudança,
-e, então, irá gravar a nova versão do projeto.
-
-Alternativamente, ao invés de executar 'git-add' antes, você pode usar
-
-------------------------------------------------
-$ git commit -a
-------------------------------------------------
-
-o que irá automaticamente notar quaisquer arquivos modificados (mas não
-novos), adicioná-los ao índices, e gravar, tudo em um único passo.
-
-Uma nota em mensagens de commit: Apesar de não ser exigido, é uma boa
-idéia começar a mensagem com uma simples e curta (menos de 50
-caracteres) linha sumarizando a mudança, seguida de uma linha em branco
-e, então, uma descrição mais detalhada. Ferramentas que transformam
-commits em email, por exemplo, usam a primeira linha no campo de
-cabeçalho "Subject:" e o resto no corpo.
-
-Git rastreia conteúdo, não arquivos
-----------------------------
-
-Muitos sistemas de controle de revisão provêem um comando `add` que diz
-ao sistema para começar a rastrear mudanças em um novo arquivo. O
-comando `add` do git faz algo mais simples e mais poderoso: 'git-add' é
-usado tanto para arquivos novos e arquivos recentemente modificados, e
-em ambos os casos, ele tira o instantâneo dos arquivos dados e armazena
-o conteúdo no índice, pronto para inclusão do próximo commit.
-
-Visualizando a história do projeto
------------------------
-
-Em qualquer ponto você pode visualizar a história das suas mudanças
-usando
-
-------------------------------------------------
-$ git log
-------------------------------------------------
-
-Se você também quiser ver a diferença completa a cada passo, use
-
-------------------------------------------------
-$ git log -p
-------------------------------------------------
-
-Geralmente, uma visão geral da mudança é útil para ter a sensação de
-cada passo
-
-------------------------------------------------
-$ git log --stat --summary
-------------------------------------------------
-
-Gerenciando "branches"/ramos
------------------
-
-Um simples repositório git pode manter múltiplos ramos de
-desenvolvimento. Para criar um novo ramo chamado "experimental", use
-
-------------------------------------------------
-$ git branch experimental
-------------------------------------------------
-
-Se você executar agora
-
-------------------------------------------------
-$ git branch
-------------------------------------------------
-
-você vai obter uma lista de todos os ramos existentes:
-
-------------------------------------------------
-  experimental
-* master
-------------------------------------------------
-
-O ramo "experimental" é o que você acaba de criar, e o ramo "master" é o
-ramo padrão que foi criado pra você automaticamente. O asterisco marca
-o ramo em que você está atualmente; digite
-
-------------------------------------------------
-$ git checkout experimental
-------------------------------------------------
-
-para mudar para o ramo experimental. Agora edite um arquivo, grave a
-mudança, e mude de volta para o ramo master:
-
-------------------------------------------------
-(edita arquivo)
-$ git commit -a
-$ git checkout master
-------------------------------------------------
-
-Verifique que a mudança que você fez não está mais visível, já que ela
-foi feita no ramo experimental e você está de volta ao ramo master.
-
-Você pode fazer uma mudança diferente no ramo master:
-
-------------------------------------------------
-(edit file)
-$ git commit -a
-------------------------------------------------
-
-neste ponto, os dois ramos divergiram, com diferentes mudanças feitas em
-cada um. Para unificar as mudanças feitas no experimental para o
-master, execute
-
-------------------------------------------------
-$ git merge experimental
-------------------------------------------------
-
-Se as mudanças não conflitarem, estará pronto. Se existirem conflitos,
-marcadores serão deixados nos arquivos problemáticos exibindo o
-conflito;
-
-------------------------------------------------
-$ git diff
-------------------------------------------------
-
-vai exibir isto. Após você editar os arquivos para resolver os
-conflitos,
-
-------------------------------------------------
-$ git commit -a
-------------------------------------------------
-
-irá gravar o resultado da unificação. Finalmente,
-
-------------------------------------------------
-$ gitk
-------------------------------------------------
-
-vai mostrar uma bela representação gráfica da história resultante.
-
-Neste ponto você pode remover seu ramo experimental com
-
-------------------------------------------------
-$ git branch -d experimental
-------------------------------------------------
-
-Este comando garante que as mudanças no ramo experimental já estão no
-ramo atual.
-
-Se você desenvolve em um ramo ideia-louca, e se arrepende, você pode
-sempre remover o ramo com
-
--------------------------------------
-$ git branch -D ideia-louca
--------------------------------------
-
-Ramos são baratos e fáceis, então isto é uma boa maneira de experimentar
-alguma coisa.
-
-Usando git para colaboração
----------------------------
-
-Suponha que Alice começou um novo projeto com um repositório git em
-/home/alice/project, e que Bob, que tem um diretório home na mesma
-máquina, quer contribuir.
-
-Bob começa com:
-
-------------------------------------------------
-bob$ git clone /home/alice/project myrepo
-------------------------------------------------
-
-Isso cria um novo diretório "myrepo" contendo um clone do repositório de
-Alice. O clone está no mesmo pé que o projeto original, possuindo sua
-própria cópia da história do projeto original.
-
-Bob então faz algumas mudanças e as grava:
-
-------------------------------------------------
-(editar arquivos)
-bob$ git commit -a
-(repetir conforme necessário)
-------------------------------------------------
-
-Quanto está pronto, ele diz a Alice para puxar as mudanças do
-repositório em /home/bob/myrepo. Ela o faz com:
-
-------------------------------------------------
-alice$ cd /home/alice/project
-alice$ git pull /home/bob/myrepo master
-------------------------------------------------
-
-Isto unifica as mudanças do ramo "master" do Bob ao ramo atual de Alice.
-Se Alice fez suas próprias mudanças no intervalo, ela, então, pode
-precisar corrigir manualmente quaisquer conflitos. (Note que o argumento
-"master" no comando acima é, de fato, desnecessário, já que é o padrão.)
-
-O comando "pull" executa, então, duas operações: ele obtém mudanças de
-um ramo remoto, e, então, as unifica no ramo atual.
-
-Note que, em geral, Alice gostaria que suas mudanças locais fossem
-gravadas antes de iniciar este "pull". Se o trabalho de Bob conflita
-com o que Alice fez desde que suas histórias se ramificaram, Alice irá
-usar seu diretório de trabalho e o índice para resolver conflitos, e
-mudanças locais existentes irão interferir com o processo de resolução
-de conflitos (git ainda irá realizar a obtenção mas irá se recusar a
-unificar --- Alice terá que se livrar de suas mudanças locais de alguma
-forma e puxar de novo quando isso acontecer).
-
-Alice pode espiar o que Bob fez sem unificar primeiro, usando o comando
-"fetch"; isto permite Alice inspecionar o que Bob fez, usando um símbolo
-especial "FETCH_HEAD", com o fim de determinar se ele tem alguma coisa
-que vale puxar, assim:
-
-------------------------------------------------
-alice$ git fetch /home/bob/myrepo master
-alice$ git log -p HEAD..FETCH_HEAD
-------------------------------------------------
-
-Esta operação é segura mesmo se Alice tem mudanças locais não gravadas.
-A notação de intervalo "HEAD..FETCH_HEAD" significa mostrar tudo que é
-alcançável de FETCH_HEAD mas exclua tudo o que é alcançável de HEAD.
-Alice já sabe tudo que leva a seu estado atual (HEAD), e revisa o que Bob
-tem em seu estado (FETCH_HEAD) que ela ainda não viu com esse comando.
-
-Se Alice quer visualizar o que Bob fez desde que suas histórias se
-ramificaram, ela pode disparar o seguinte comando:
-
-------------------------------------------------
-$ gitk HEAD..FETCH_HEAD
-------------------------------------------------
-
-Isto usa a mesma notação de intervalo que vimos antes com 'git log'.
-
-Alice pode querer ver o que ambos fizeram desde que ramificaram. Ela
-pode usar a forma com três pontos ao invés da forma com dois pontos:
-
-------------------------------------------------
-$ gitk HEAD...FETCH_HEAD
-------------------------------------------------
-
-Isto significa "mostre tudo que é alcançável de qualquer um deles, mas
-exclua tudo que é alcançável a partir de ambos".
-
-Por favor, note que essas notações de intervalo podem ser usadas tanto
-com gitk quanto com "git log".
-
-Após inspecionar o que Bob fez, se não há nada urgente, Alice pode
-decidir continuar trabalhando sem puxar de Bob. Se a história de Bob
-tem alguma coisa que Alice precisa imediatamente, Alice pode optar por
-separar seu trabalho em progresso primeiro, fazer um "pull", e, então,
-finalmente, retomar seu trabalho em progresso em cima da história
-resultante.
-
-Quando você está trabalhando em um pequeno grupo unido, não é incomum
-interagir com o mesmo repositório várias e várias vezes. Definindo um
-repositório remoto antes de tudo, você pode fazê-lo mais facilmente:
-
-------------------------------------------------
-alice$ git remote add bob /home/bob/myrepo
-------------------------------------------------
-
-Com isso, Alice pode executar a primeira parte da operação "pull" usando
-o comando 'git-fetch' sem unificar suas mudanças com seu próprio ramo,
-usando:
-
--------------------------------------
-alice$ git fetch bob
--------------------------------------
-
-Diferente da forma longa, quando Alice obteve de Bob usando um
-repositório remoto antes definido com 'git-remote', o que foi obtido é
-armazenado em um ramo remoto, neste caso `bob/master`. Então, após isso:
-
--------------------------------------
-alice$ git log -p master..bob/master
--------------------------------------
-
-mostra uma lista de todas as mudanças que Bob fez desde que ramificou do
-ramo master de Alice.
-
-Após examinar essas mudanças, Alice pode unificá-las em seu ramo master:
-
--------------------------------------
-alice$ git merge bob/master
--------------------------------------
-
-Esse `merge` pode também ser feito puxando de seu próprio ramo remoto,
-assim:
-
--------------------------------------
-alice$ git pull . remotes/bob/master
--------------------------------------
-
-Note que 'git pull' sempre unifica ao ramo atual, independente do que
-mais foi passado na linha de comando.
-
-Depois, Bob pode atualizar seu repositório com as últimas mudanças de
-Alice, usando
-
--------------------------------------
-bob$ git pull
--------------------------------------
-
-Note que ele não precisa dar o caminho do repositório de Alice; quando
-Bob clonou seu repositório, o git armazenou a localização de seu
-repositório na configuração do mesmo, e essa localização é usada
-para puxar:
-
--------------------------------------
-bob$ git config --get remote.origin.url
-/home/alice/project
--------------------------------------
-
-(A configuração completa criada por 'git-clone' é visível usando `git
-config -l`, e a página de manual linkgit:git-config[1] explica o
-significado de cada opção.)
-
-Git também mantém uma cópia limpa do ramo master de Alice sob o nome
-"origin/master":
-
--------------------------------------
-bob$ git branch -r
-  origin/master
--------------------------------------
-
-Se Bob decidir depois em trabalhar em um host diferente, ele ainda pode
-executar clones e puxar usando o protocolo ssh:
-
--------------------------------------
-bob$ git clone alice.org:/home/alice/project myrepo
--------------------------------------
-
-Alternativamente, o git tem um protocolo nativo, ou pode usar rsync ou
-http; veja linkgit:git-pull[1] para detalhes.
-
-Git pode também ser usado em um modo parecido com CVS, com um
-repositório central para o qual vários usuários empurram modificações;
-veja linkgit:git-push[1] e linkgit:gitcvs-migration[7].
-
-Explorando história
------------------
-
-A história no git é representada como uma série de commits
-interrelacionados. Nós já vimos que o comando 'git-log' pode listar
-esses commits. Note que a primeira linha de cada entrada no log também
-dá o nome para o commit:
-
--------------------------------------
-$ git log
-commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
-Author: Junio C Hamano <junkio@cox.net>
-Date:   Tue May 16 17:18:22 2006 -0700
-
-    merge-base: Clarify the comments on post processing.
--------------------------------------
-
-Nós podemos dar este nome ao 'git-show' para ver os detalhes sobre este
-commit.
-
--------------------------------------
-$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
--------------------------------------
-
-Mas há outras formas de se referir aos commits. Você pode usar qualquer
-parte inicial do nome que seja longo o bastante para identificar
-unicamente o commit:
-
--------------------------------------
-$ git show c82a22c39c	# os primeiros caracteres do nome são o bastante
-			# usualmente
-$ git show HEAD		# a ponta do ramo atual
-$ git show experimental	# a ponta do ramo "experimental"
--------------------------------------
-
-Todo commit normalmente tem um commit "pai" que aponta para o estado
-anterior do projeto:
-
--------------------------------------
-$ git show HEAD^  # para ver o pai de HEAD
-$ git show HEAD^^ # para ver o avô de HEAD
-$ git show HEAD~4 # para ver o trisavô de HEAD
--------------------------------------
-
-Note que commits de unificação podem ter mais de um pai:
-
--------------------------------------
-$ git show HEAD^1 # mostra o primeiro pai de HEAD (o mesmo que HEAD^)
-$ git show HEAD^2 # mostra o segundo pai de HEAD
--------------------------------------
-
-Você também pode dar aos commits nomes à sua escolha; após executar
-
--------------------------------------
-$ git tag v2.5 1b2e1d63ff
--------------------------------------
-
-você pode se referir a 1b2e1d63ff pelo nome "v2.5". Se você pretende
-compartilhar esse nome com outras pessoas (por exemplo, para identificar
-uma versão de lançamento), você deveria criar um objeto "tag", e talvez
-assiná-lo; veja linkgit:git-tag[1] para detalhes.
-
-Qualquer comando git que precise conhecer um commit pode receber
-quaisquer desses nomes. Por exemplo:
-
--------------------------------------
-$ git diff v2.5 HEAD	 # compara o HEAD atual com v2.5
-$ git branch stable v2.5 # inicia um novo ramo chamado "stable" baseado
-			 # em v2.5
-$ git reset --hard HEAD^ # reseta seu ramo atual e seu diretório de
-			 # trabalho a seu estado em HEAD^
--------------------------------------
-
-Seja cuidadoso com o último comando: além de perder quaisquer mudanças
-em seu diretório de trabalho, ele também remove todos os commits
-posteriores desse ramo. Se esse ramo é o único ramo contendo esses
-commits, eles serão perdidos. Também, não use 'git-reset' num ramo
-publicamente visível de onde outros desenvolvedores puxam, já que vai
-forçar unificações desnecessárias para que outros desenvolvedores limpem
-a história. Se você precisa desfazer mudanças que você empurrou, use
-'git-revert' no lugar.
-
-O comando 'git-grep' pode buscar strings em qualquer versão de seu
-projeto, então
-
--------------------------------------
-$ git grep "hello" v2.5
--------------------------------------
-
-procura por todas as ocorrências de "hello" em v2.5.
-
-Se você deixar de fora o nome do commit, 'git-grep' irá procurar
-quaisquer dos arquivos que ele gerencia no diretório corrente. Então
-
--------------------------------------
-$ git grep "hello"
--------------------------------------
-
-é uma forma rápida de buscar somente os arquivos que são rastreados pelo
-git.
-
-Muitos comandos git também recebem um conjunto de commits, o que pode
-ser especificado de várias formas. Aqui estão alguns exemplos com 'git-log':
-
--------------------------------------
-$ git log v2.5..v2.6            # commits entre v2.5 e v2.6
-$ git log v2.5..                # commits desde v2.5
-$ git log --since="2 weeks ago" # commits das últimas 2 semanas
-$ git log v2.5.. Makefile       # commits desde v2.5 que modificam
-				# Makefile
--------------------------------------
-
-Você também pode dar ao 'git-log' um "intervalo" de commits onde o
-primeiro não é necessariamente um ancestral do segundo; por exemplo, se
-as pontas dos ramos "stable" e "master" divergiram de um commit
-comum algum tempo atrás, então
-
--------------------------------------
-$ git log stable..master
--------------------------------------
-
-irá listar os commits feitos no ramo "master" mas não no ramo
-"stable", enquanto
-
--------------------------------------
-$ git log master..stable
--------------------------------------
-
-irá listar a lista de commits feitos no ramo "stable" mas não no ramo
-"master".
-
-O comando 'git-log' tem uma fraqueza: ele precisa mostrar os commits em
-uma lista. Quando a história tem linhas de desenvolvimento que
-divergiram e então foram unificadas novamente, a ordem em que 'git-log'
-apresenta essas mudanças é irrelevante.
-
-A maioria dos projetos com múltiplos contribuidores (como o kernel
-Linux, ou o próprio git) tem unificações frequentes, e 'gitk' faz um
-trabalho melhor de visualizar sua história. Por exemplo,
-
--------------------------------------
-$ gitk --since="2 weeks ago" drivers/
--------------------------------------
-
-permite a você navegar em quaisquer commits desde as últimas duas semanas
-de commits que modificaram arquivos sob o diretório "drivers". (Nota:
-você pode ajustar as fontes do gitk segurando a tecla control enquanto
-pressiona "-" ou "+".)
-
-Finalmente, a maioria dos comandos que recebem nomes de arquivo permitirão
-também, opcionalmente, preceder qualquer nome de arquivo por um
-commit, para especificar uma versão particular do arquivo:
-
--------------------------------------
-$ git diff v2.5:Makefile HEAD:Makefile.in
--------------------------------------
-
-Você pode usar 'git-show' para ver tal arquivo:
-
--------------------------------------
-$ git show v2.5:Makefile
--------------------------------------
-
-Próximos passos

-
-Este tutorial deve ser o bastante para operar controle de revisão
-distribuído básico para seus projetos. No entanto, para entender
-plenamente a profundidade e o poder do git você precisa entender duas
-idéias simples nas quais ele se baseia:
-
-  * A base de objetos é um sistema bem elegante usado para armazenar a
-    história de seu projeto--arquivos, diretórios, e commits.
-
-  * O arquivo de índice é um cache do estado de uma árvore de diretório,
-    usado para criar commits, restaurar diretórios de trabalho, e
-    armazenar as várias árvores envolvidas em uma unificação.
-
-A parte dois deste tutorial explica a base de objetos, o arquivo de
-índice, e algumas outras coisinhas que você vai precisar pra usar o
-máximo do git. Você pode encontrá-la em linkgit:gittutorial-2[7].
-
-Se você não quiser continuar com o tutorial agora nesse momento, algumas
-outras digressões que podem ser interessantes neste ponto são:
-
-  * linkgit:git-format-patch[1], linkgit:git-am[1]: Estes convertem
-    séries de commits em patches para email, e vice-versa, úteis para
-    projetos como o kernel Linux que dependem fortemente de patches
-    enviados por email.
-
-  * linkgit:git-bisect[1]: Quando há uma regressão em seu projeto, uma
-    forma de rastrear um bug é procurando pela história para encontrar o
-    commit culpado. Git bisect pode ajudar a executar uma busca binária
-    por esse commit. Ele é inteligente o bastante para executar uma
-    busca próxima da ótima mesmo no caso de uma história complexa
-    não-linear com muitos ramos unificados.

+As explained in the comments, you can reorder commits, squash them
+together, edit commit messages, etc. by editing the list.  Once you
+are satisfied, save the list and close your editor, and the rebase
+will begin.
+
+The rebase will stop where `pick` has been replaced with `edit` or
+when a step in the list fails to mechanically resolve conflicts and

- * At start up, we are trying to determine whether Win32 API or cygwin stat
- * functions should be used. The choice is determined by core.ignorecygwinfstricks.
- * Reading this option is not always possible immediately as git_dir may
- * not be set yet. So until it is set, use cygwin lstat/stat functions.
- * However, if core.filemode is set, we must use the Cygwin posix
- * stat/lstat as the Windows stat functions do not determine posix filemode.
- *
- * Note that git_cygwin_config() does NOT call git_default_config() and this
- * is deliberate.  Many commands read from config to establish initial
- * values in variables and later tweak them from elsewhere (e.g. command line).
- * init_stat() is called lazily on demand, typically much late in the program,
- * and calling git_default_config() from here would break such variables.

+NAME
+----
+git-contacts - List people who might be interested in a set of changes
+
+
+SYNOPSIS
+--------
+[verse]
+'git contacts' (<patch>|<range>|<rev>)...
+
+
+DESCRIPTION
+-----------
+
+Given a set of changes, specified as patch files or revisions, determine people
+who might be interested in those changes.  This is done by consulting the
+history of each patch or revision hunk to find people mentioned by commits
+which touched the lines of files under consideration.
+
+Input consists of one or more patch files or revision arguments.  A revision
+argument can be a range or a single `<rev>` which is interpreted as
+`<rev>..HEAD`, thus the same revision arguments are accepted as for
+linkgit:git-format-patch[1]. Patch files and revision arguments can be combined
+in the same invocation.
+
+This command can be useful for determining the list of people with whom to
+discuss proposed changes, or for finding the list of recipients to Cc: when
+submitting a patch series via `git send-email`. For the latter case, `git
+contacts` can be used as the argument to `git send-email`'s `--cc-cmd` option.
+
+
+DISCUSSION
+----------
+
+`git blame` is invoked for each hunk in a patch file or revision.  For each
+commit mentioned by `git blame`, the commit message is consulted for people who
+authored, reviewed, signed, acknowledged, or were Cc:'d.  Once the list of
+participants is known, each person's relevance is computed by considering how
+many commits mentioned that person compared with the total number of commits
+under consideration.  The final output consists only of participants who exceed
+a minimum threshold of participation.
+
+
+OUTPUT
+------
+
+For each person of interest, a single line is output, terminated by a newline.
+If the person's name is known, ``Name $$<user@host>$$'' is printed; otherwise
+only ``$$<user@host>$$'' is printed.
+
+
+EXAMPLES
+--------
+
+* Consult patch files:
++
+------------
+$ git contacts feature/*.patch
+------------
+
+* Revision range:
++
+------------
+$ git contacts R1..R2
+------------
+
+* From a single revision to `HEAD`:
++
+------------
+$ git contacts origin
+------------
+
+* Helper for `git send-email`:
++
+------------
+$ git send-email --cc-cmd='git contacts' feature/*.patch
+------------
+
+
+LIMITATIONS
+-----------
+
+Several conditions controlling a person's significance are currently
+hard-coded, such as minimum participation level (10%), blame date-limiting (5
+years), and `-C` level for detecting moved and copied lines (a single `-C`). In
+the future, these conditions may become configurable.

-#!/usr/bin/perl
-#
-# A daemon that waits for update events sent by its companion
-# post-receive-cinotify hook, checks out a new copy of source,
-# compiles it, and emails the guilty parties if the compile
-# (and optionally test suite) fails.
-#
-# To use this daemon, configure it and run it.  It will disconnect
-# from your terminal and fork into the background.  The daemon must
-# have local filesystem access to the source repositories, as it
-# uses objects/info/alternates to avoid copying objects.
-#
-# Add its companion post-receive-cinotify hook as the post-receive
-# hook to each repository that the daemon should monitor.  Yes, a
-# single daemon can monitor more than one repository.
-#
-# To use multiple daemons on the same system, give them each a
-# unique queue file and tmpdir.
-#
-# Global Config
-# -------------
-# Reads from a Git style configuration file.  This will be
-# ~/.gitconfig by default but can be overridden by setting
-# the GIT_CONFIG_FILE environment variable before starting.
-#
-# cidaemon.smtpHost
-#   Hostname of the SMTP server the daemon will send email
-#   through.  Defaults to 'localhost'.
-#
-# cidaemon.smtpUser
-#   Username to authenticate to the SMTP server as.  This
-#   variable is optional; if it is not supplied then no
-#   authentication will be performed.
-#
-# cidaemon.smtpPassword
-#   Password to authenticate to the SMTP server as.  This
-#   variable is optional.  If not supplied but smtpUser was,
-#   the daemon prompts for the password before forking into
-#   the background.
-#
-# cidaemon.smtpAuth
-#   Type of authentication to perform with the SMTP server.
-#   If set to 'login' and smtpUser was defined, this will
-#   use the AUTH LOGIN command, which is suitable for use
-#   with at least one version of Microsoft Exchange Server.
-#   If not set the daemon will use whatever auth methods
-#   are supported by your version of Net::SMTP.
-#
-# cidaemon.email
-#   Email address that daemon generated emails will be sent
-#   from.  This should be a useful email address within your
-#   organization.  Required.
-#
-# cidaemon.name
-#   Human friendly name that the daemon will send emails as.
-#   Defaults to 'cidaemon'.
-#
-# cidaemon.scanDelay
-#   Number of seconds to sleep between polls of the queue file.
-#   Defaults to 60.
-#
-# cidaemon.recentCache
-#   Number of recent commit SHA-1s per repository to cache and
-#   skip building if they appear again.  This is useful to avoid
-#   rebuilding the same commit multiple times just because it was
-#   pushed into more than one branch.  Defaults to 100.
-#
-# cidaemon.tmpdir
-#   Scratch directory to create the builds within.  The daemon
-#   makes a new subdirectory for each build, then deletes it when
-#   the build has finished.  The pid file is also placed here.
-#   Defaults to '/tmp'.
-#
-# cidaemon.queue
-#   Path to the queue file that the post-receive-cinotify hook
-#   appends events to.  This file is polled by the daemon.  It
-#   must not be on an NFS mount (uses flock).  Required.
-#
-# cidaemon.nocc
-#   Perl regex patterns to match against author and committer
-#   lines.  If a pattern matches, that author or committer will
-#   not be notified of a build failure.
-#
-# Per Repository Config
-# ----------------------
-# Read from the source repository's config file.
-#
-# builder.command
-#   Shell command to execute the build.  This command must
-#   return 0 on "success" and non-zero on failure.  If you
-#   also want to run a test suite, make sure your command
-#   does that too.  Required.
-#
-# builder.queue
-#   Queue file to notify the cidaemon through.  Should match
-#   cidaemon.queue.  If not set the hook will not notify the
-#   cidaemon.
-#
-# builder.skip
-#   Perl regex patterns of refs that should not be sent to
-#   cidaemon.  Updates of these refs will be ignored.
-#
-# builder.newBranchBase
-#   Glob patterns of refs that should be used to form the
-#   'old' revions of a newly created ref.  This should set
-#   to be globs that match your 'mainline' branches.  This
-#   way a build failure of a brand new topic branch does not
-#   attempt to email everyone since the beginning of time;
-#   instead it only emails those authors of commits not in
-#   these 'mainline' branches.

+Options:
+
+  -f|--file AUTHFILE : specify netrc-style files.  Files with the .gpg extension
+                       will be decrypted by GPG before parsing.  Multiple -f
+                       arguments are OK.  They are processed in order, and the
+                       first matching entry found is returned via the credential
+                       helper protocol (see below).
+
+                       When no -f option is given, .authinfo.gpg, .netrc.gpg,
+		       .authinfo, and .netrc files in your home directory are used
+		       in this order.
+
+  -k|--insecure      : ignore bad file ownership or permissions
+
+  -d|--debug         : turn on debugging (developer info)
+
+  -v|--verbose       : be more verbose (show files and information found)
+
+To enable this credential helper:
+
+  git config credential.helper '$shortname -f AUTHFILE1 -f AUTHFILE2'
+
+(Note that Git will prepend "git-credential-" to the helper name and look for it
+in the path.)
+
+...and if you want lots of debugging info:
+
+  git config credential.helper '$shortname -f AUTHFILE -d'
+
+...or to see the files opened and data found:
+
+  git config credential.helper '$shortname -f AUTHFILE -v'
+
+Only "get" mode is supported by this credential helper.  It opens every AUTHFILE
+and looks for the first entry that matches the requested search criteria:
+
+ 'port|protocol':
+   The protocol that will be used (e.g., https). (protocol=X)
+
+ 'machine|host':
+   The remote hostname for a network credential. (host=X)
+
+ 'path':
+   The path with which the credential will be used. (path=X)
+
+ 'login|user|username':
+   The credential’s username, if we already have one. (username=X)
+
+Thus, when we get this query on STDIN:
+
+host=github.com
+protocol=https
+username=tzz
+
+this credential helper will look for the first entry in every AUTHFILE that
+matches
+
+machine github.com port https login tzz
+
+OR
+
+machine github.com protocol https login tzz
+
+OR... etc. acceptable tokens as listed above.  Any unknown tokens are
+simply ignored.
+
+Then, the helper will print out whatever tokens it got from the entry, including
+"password" tokens, mapping back to Git's helper protocol; e.g. "port" is mapped
+back to "protocol".  Any redundant entry tokens (part of the original query) are
+skipped.
+
+Again, note that only the first matching entry from all the AUTHFILEs, processed
+in the sequence given on the command line, is used.
+
+Netrc/authinfo tokens can be quoted as 'STRING' or "STRING".
+
+No caching is performed by this credential helper.

+			   git-multimail
+			   =============
+
+git-multimail is a tool for sending notification emails on pushes to a
+Git repository.  It includes a Python module called git_multimail.py,
+which can either be used as a hook script directly or can be imported
+as a Python module into another script.
+
+git-multimail is derived from the Git project's old
+contrib/hooks/post-receive-email, and is mostly compatible with that
+script.  See README.migrate-from-post-receive-email for details about
+the differences and for how to migrate from post-receive-email to
+git-multimail.
+
+git-multimail, like the rest of the Git project, is licensed under
+GPLv2 (see the COPYING file for details).
+
+Please note: although, as a convenience, git-multimail may be
+distributed along with the main Git project, development of
+git-multimail takes place in its own, separate project.  See section
+"Getting involved" below for more information.
+
+
+By default, for each push received by the repository, git-multimail:
+
+1. Outputs one email summarizing each reference that was changed.
+   These "reference change" (called "refchange" below) emails describe
+   the nature of the change (e.g., was the reference created, deleted,
+   fast-forwarded, etc.) and include a one-line summary of each commit
+   that was added to the reference.
+
+2. Outputs one email for each new commit that was introduced by the
+   reference change.  These "commit" emails include a list of the
+   files changed by the commit, followed by the diffs of files
+   modified by the commit.  The commit emails are threaded to the
+   corresponding reference change email via "In-Reply-To".  This style
+   (similar to the "git format-patch" style used on the Git mailing
+   list) makes it easy to scan through the emails, jump to patches
+   that need further attention, and write comments about specific
+   commits.  Commits are handled in reverse topological order (i.e.,
+   parents shown before children).  For example,
+
+   [git] branch master updated
+   + [git] 01/08: doc: fix xref link from api docs to manual pages
+   + [git] 02/08: api-credentials.txt: show the big picture first
+   + [git] 03/08: api-credentials.txt: mention credential.helper explicitly
+   + [git] 04/08: api-credentials.txt: add "see also" section
+   + [git] 05/08: t3510 (cherry-pick-sequence): add missing '&&'
+   + [git] 06/08: Merge branch 'rr/maint-t3510-cascade-fix'
+   + [git] 07/08: Merge branch 'mm/api-credentials-doc'
+   + [git] 08/08: Git 1.7.11-rc2
+
+   Each commit appears in exactly one commit email, the first time
+   that it is pushed to the repository.  If a commit is later merged
+   into another branch, then a one-line summary of the commit is
+   included in the reference change email (as usual), but no
+   additional commit email is generated.
+
+   By default, reference change emails have their "Reply-To" field set
+   to the person who pushed the change, and commit emails have their
+   "Reply-To" field set to the author of the commit.
+
+3. Output one "announce" mail for each new annotated tag, including
+   information about the tag and optionally a shortlog describing the
+   changes since the previous tag.  Such emails might be useful if you
+   use annotated tags to mark releases of your project.
+
+
+Requirements
+------------
+
+* Python 2.x, version 2.4 or later.  No non-standard Python modules
+  are required.  git-multimail does *not* currently work with Python
+  3.x.
+
+  The example scripts invoke Python using the following shebang line
+  (following PEP 394 [1]):
+
+      #! /usr/bin/env python2
+
+  If your system's Python2 interpreter is not in your PATH or is not
+  called "python2", you can change the lines accordingly.  Or you can
+  invoke the Python interpreter explicitly, for example via a tiny
+  shell script like
+
+      #! /bin/sh
+      /usr/local/bin/python /path/to/git_multimail.py "$@"
+
+* The "git" command must be in your PATH.  git-multimail is known to
+  work with Git versions back to 1.7.1.  (Earlier versions have not
+  been tested; if you do so, please report your results.)
+
+* To send emails using the default configuration, a standard sendmail
+  program must be located at '/usr/sbin/sendmail' and configured
+  correctly to send emails.  If this is not the case, see the
+  multimailhook.mailer configuration variable below for how to
+  configure git-multimail to send emails via an SMTP server.
+
+
+Invocation
+----------
+
+git_multimail.py is designed to be used as a "post-receive" hook in a
+Git repository (see githooks(5)).  Link or copy it to
+$GIT_DIR/hooks/post-receive within the repository for which email
+notifications are desired.  Usually it should be installed on the
+central repository for a project, to which all commits are eventually
+pushed.
+
+For use on pre-v1.5.1 Git servers, git_multimail.py can also work as
+an "update" hook, taking its arguments on the command line.  To use
+this script in this manner, link or copy it to $GIT_DIR/hooks/update.
+Please note that the script is not completely reliable in this mode
+[2].
+
+Alternatively, git_multimail.py can be imported as a Python module
+into your own Python post-receive script.  This method is a bit more
+work, but allows the behavior of the hook to be customized using
+arbitrary Python code.  For example, you can use a custom environment
+(perhaps inheriting from GenericEnvironment or GitoliteEnvironment) to
+
+* change how the user who did the push is determined
+
+* read users' email addresses from an LDAP server or from a database
+
+* decide which users should be notified about which commits based on
+  the contents of the commits (e.g., for users who want to be notified
+  only about changes affecting particular files or subdirectories)
+
+Or you can change how emails are sent by writing your own Mailer
+class.  The "post-receive" script in this directory demonstrates how
+to use git_multimail.py as a Python module.  (If you make interesting
+changes of this type, please consider sharing them with the
+community.)
+
+
+Configuration
+-------------
+
+By default, git-multimail mostly takes its configuration from the
+following "git config" settings:
+
+multimailhook.environment
+
+    This describes the general environment of the repository.
+    Currently supported values:
+
+    "generic" -- the username of the pusher is read from $USER and the
+        repository name is derived from the repository's path.
+
+    "gitolite" -- the username of the pusher is read from $GL_USER and
+        the repository name from $GL_REPO.
+
+    If neither of these environments is suitable for your setup, then
+    you can implement a Python class that inherits from Environment
+    and instantiate it via a script that looks like the example
+    post-receive script.
+
+    The environment value can be specified on the command line using
+    the --environment option.  If it is not specified on the command
+    line or by multimailhook.environment, then it defaults to
+    "gitolite" if the environment contains variables $GL_USER and
+    $GL_REPO; otherwise "generic".
+
+multimailhook.repoName
+
+    A short name of this Git repository, to be used in various places
+    in the notification email text.  The default is to use $GL_REPO
+    for gitolite repositories, or otherwise to derive this value from
+    the repository path name.
+
+multimailhook.mailinglist
+
+    The list of email addresses to which notification emails should be
+    sent, as RFC 2822 email addresses separated by commas.  This
+    configuration option can be multivalued.  Leave it unset or set it
+    to the empty string to not send emails by default.  The next few
+    settings can be used to configure specific address lists for
+    specific types of notification email.
+
+multimailhook.refchangeList
+
+    The list of email addresses to which summary emails about
+    reference changes should be sent, as RFC 2822 email addresses
+    separated by commas.  This configuration option can be
+    multivalued.  The default is the value in
+    multimailhook.mailinglist.  Set this value to the empty string to
+    prevent reference change emails from being sent.
+
+multimailhook.announceList
+
+    The list of email addresses to which emails about new annotated
+    tags should be sent, as RFC 2822 email addresses separated by
+    commas.  This configuration option can be multivalued.  The
+    default is the value in multimailhook.refchangelist or
+    multimailhook.mailinglist.  Set this value to the empty string to
+    prevent annotated tag announcement emails from being sent.
+
+multimailhook.commitList
+
+    The list of email addresses to which emails about individual new
+    commits should be sent, as RFC 2822 email addresses separated by
+    commas.  This configuration option can be multivalued.  The
+    default is the value in multimailhook.mailinglist.  Set this value
+    to the empty string to prevent notification emails about
+    individual commits from being sent.
+
+multimailhook.announceShortlog
+
+    If this option is set to true, then emails about changes to
+    annotated tags include a shortlog of changes since the previous
+    tag.  This can be useful if the annotated tags represent releases;
+    then the shortlog will be a kind of rough summary of what has
+    happened since the last release.  But if your tagging policy is
+    not so straightforward, then the shortlog might be confusing
+    rather than useful.  Default is false.
+
+multimailhook.refchangeShowLog
+
+    If this option is set to true, then summary emails about reference
+    changes will include a detailed log of the added commits in
+    addition to the one line summary.  The log is generated by running
+    "git log" with the options specified in multimailhook.logOpts.
+    Default is false.
+
+multimailhook.mailer
+
+    This option changes the way emails are sent.  Accepted values are:
+
+    - sendmail (the default): use the command /usr/sbin/sendmail or
+      /usr/lib/sendmail (or sendmailCommand, if configured).  This
+      mode can be further customized via the following options:
+
+       multimailhook.sendmailCommand
+
+           The command used by mailer "sendmail" to send emails.  Shell
+           quoting is allowed in the value of this setting, but remember that
+           Git requires double-quotes to be escaped; e.g.,
+
+             git config multimailhook.sendmailcommand '/usr/sbin/sendmail -t -F \"Git Repo\"'
+
+           Default is '/usr/sbin/sendmail -t' or '/usr/lib/sendmail
+           -t' (depending on which file is present and executable).
+
+       multimailhook.envelopeSender
+
+           If set then pass this value to sendmail via the -f option to set
+           the envelope sender address.
+
+    - smtp: use Python's smtplib.  This is useful when the sendmail
+      command is not available on the system.  This mode can be
+      further customized via the following options:
+
+       multimailhook.smtpServer
+
+           The name of the SMTP server to connect to.  The value can
+           also include a colon and a port number; e.g.,
+           "mail.example.com:25".  Default is 'localhost' using port
+           25.
+
+       multimailhook.envelopeSender
+
+           The sender address to be passed to the SMTP server.  If
+           unset, then the value of multimailhook.from is used.
+
+multimailhook.from
+
+    If set then use this value in the From: field of generated emails.
+    If unset, then use the repository's user configuration (user.name
+    and user.email).  If user.email is also unset, then use
+    multimailhook.envelopeSender.
+
+multimailhook.administrator
+
+    The name and/or email address of the administrator of the Git
+    repository; used in FOOTER_TEMPLATE.  Default is
+    multimailhook.envelopesender if it is set; otherwise a generic
+    string is used.
+
+multimailhook.emailPrefix
+
+    All emails have this string prepended to their subjects, to aid
+    email filtering (though filtering based on the X-Git-* email
+    headers is probably more robust).  Default is the short name of
+    the repository in square brackets; e.g., "[myrepo]".
+
+multimailhook.emailMaxLines
+
+    The maximum number of lines that should be included in the body of
+    a generated email.  If not specified, there is no limit.  Lines
+    beyond the limit are suppressed and counted, and a final line is
+    added indicating the number of suppressed lines.
+
+multimailhook.emailMaxLineLength
+
+    The maximum length of a line in the email body.  Lines longer than
+    this limit are truncated to this length with a trailing " [...]"
+    added to indicate the missing text.  The default is 500, because
+    (a) diffs with longer lines are probably from binary files, for
+    which a diff is useless, and (b) even if a text file has such long
+    lines, the diffs are probably unreadable anyway.  To disable line
+    truncation, set this option to 0.
+
+multimailhook.maxCommitEmails
+
+    The maximum number of commit emails to send for a given change.
+    When the number of patches is larger that this value, only the
+    summary refchange email is sent.  This can avoid accidental
+    mailbombing, for example on an initial push.  To disable commit
+    emails limit, set this option to 0.  The default is 500.
+
+multimailhook.emailStrictUTF8
+
+    If this boolean option is set to "true", then the main part of the
+    email body is forced to be valid UTF-8.  Any characters that are
+    not valid UTF-8 are converted to the Unicode replacement
+    character, U+FFFD.  The default is "true".
+
+multimailhook.diffOpts
+
+    Options passed to "git diff-tree" when generating the summary
+    information for ReferenceChange emails.  Default is "--stat
+    --summary --find-copies-harder".  Add -p to those options to
+    include a unified diff of changes in addition to the usual summary
+    output.  Shell quoting is allowed; see multimailhook.logOpts for
+    details.
+
+multimailhook.logOpts
+
+    Options passed to "git log" to generate additional info for
+    reference change emails (used only if refchangeShowLog is set).
+    For example, adding --graph will show the graph of revisions, -p
+    will show the complete diff, etc.  The default is empty.
+
+    Shell quoting is allowed; for example, a log format that contains
+    spaces can be specified using something like:
+
+      git config multimailhook.logopts '--pretty=format:"%h %aN <%aE>%n%s%n%n%b%n"'
+
+    If you want to set this by editing your configuration file
+    directly, remember that Git requires double-quotes to be escaped
+    (see git-config(1) for more information):
+
+      [multimailhook]
+              logopts = --pretty=format:\"%h %aN <%aE>%n%s%n%n%b%n\"
+
+multimailhook.emailDomain
+
+    Domain name appended to the username of the person doing the push
+    to convert it into an email address (via "%s@%s" % (username,
+    emaildomain)).  More complicated schemes can be implemented by
+    overriding Environment and overriding its get_pusher_email()
+    method.
+
+multimailhook.replyTo
+multimailhook.replyToCommit
+multimailhook.replyToRefchange
+
+    Addresses to use in the Reply-To: field for commit emails
+    (replyToCommit) and refchange emails (replyToRefchange).
+    multimailhook.replyTo is used as default when replyToCommit or
+    replyToRefchange is not set.  The value for these variables can be
+    either:
+
+    - An email address, which will be used directly.
+
+    - The value "pusher", in which case the pusher's address (if
+      available) will be used.  This is the default for refchange
+      emails.
+
+    - The value "author" (meaningful only for replyToCommit), in which
+      case the commit author's address will be used.  This is the
+      default for commit emails.
+
+    - The value "none", in which case the Reply-To: field will be
+      omitted.
+
+
+Email filtering aids
+--------------------
+
+All emails include extra headers to enable fine tuned filtering and
+give information for debugging.  All emails include the headers
+"X-Git-Repo", "X-Git-Refname", and "X-Git-Reftype".  ReferenceChange
+emails also include headers "X-Git-Oldrev" and "X-Git-Newrev";
+Revision emails also include header "X-Git-Rev".
+
+
+Customizing email contents
+--------------------------
+
+git-multimail mostly generates emails by expanding templates.  The
+templates can be customized.  To avoid the need to edit
+git_multimail.py directly, the preferred way to change the templates
+is to write a separate Python script that imports git_multimail.py as
+a module, then replaces the templates in place.  See the provided
+post-receive script for an example of how this is done.
+
+
+Customizing git-multimail for your environment
+----------------------------------------------
+
+git-multimail is mostly customized via an "environment" that describes
+the local environment in which Git is running.  Two types of
+environment are built in:
+
+* GenericEnvironment: a stand-alone Git repository.
+
+* GitoliteEnvironment: a Git repository that is managed by gitolite
+  [3].  For such repositories, the identity of the pusher is read from
+  environment variable $GL_USER, and the name of the repository is
+  read from $GL_REPO (if it is not overridden by
+  multimailhook.reponame).
+
+By default, git-multimail assumes GitoliteEnvironment if $GL_USER and
+$GL_REPO are set, and otherwise assumes GenericEnvironment.
+Alternatively, you can choose one of these two environments explicitly
+by setting a "multimailhook.environment" config setting (which can
+have the value "generic" or "gitolite") or by passing an --environment
+option to the script.
+
+If you need to customize the script in ways that are not supported by
+the existing environments, you can define your own environment class
+class using arbitrary Python code.  To do so, you need to import
+git_multimail.py as a Python module, as demonstrated by the example
+post-receive script.  Then implement your environment class; it should
+usually inherit from one of the existing Environment classes and
+possibly one or more of the EnvironmentMixin classes.  Then set the
+"environment" variable to an instance of your own environment class
+and pass it to run_as_post_receive_hook().
+
+The standard environment classes, GenericEnvironment and
+GitoliteEnvironment, are in fact themselves put together out of a
+number of mixin classes, each of which handles one aspect of the
+customization.  For the finest control over your configuration, you
+can specify exactly which mixin classes your own environment class
+should inherit from, and override individual methods (or even add your
+own mixin classes) to implement entirely new behaviors.  If you
+implement any mixins that might be useful to other people, please
+consider sharing them with the community!
+
+
+Getting involved
+----------------
+
+git-multimail is an open-source project, built by volunteers.  We
+would welcome your help!
+
+The current maintainer is Michael Haggerty <mhagger@alum.mit.edu>.
+
+General discussion of git-multimail takes place on the main Git
+mailing list,
+
+    git@vger.kernel.org
+
+Please CC emails regarding git-multimail to me so that I don't
+overlook them.
+
+The git-multimail project itself is currently hosted on GitHub:
+
+    https://github.com/mhagger/git-multimail
+
+We use the GitHub issue tracker to keep track of bugs and feature

+git-multimail is close to, but not exactly, a plug-in replacement for
+the old Git project script contrib/hooks/post-receive-email.  This
+document describes the differences and explains how to configure
+git-multimail to get behavior closest to that of post-receive-email.
+
+If you are in a hurry
+=====================
+
+A script called migrate-mailhook-config is included with
+git-multimail.  If you run this script within a Git repository that is
+configured to use post-receive-email, it will convert the
+configuration settings into the approximate equivalent settings for
+git-multimail.  For more information, run
+
+    migrate-mailhook-config --help
+
+
+Configuration differences
+=========================
+
+* The names of the config options for git-multimail are in namespace
+  "multimailhook.*" instead of "hooks.*".  (Editorial comment:
+  post-receive-email should never have used such a generic top-level
+  namespace.)
+
+* In emails about new annotated tags, post-receive-email includes a
+  shortlog of all changes since the previous annotated tag.  To get
+  this behavior with git-multimail, you need to set
+  multimailhook.announceshortlog to true:
+
+      git config multimailhook.announceshortlog true
+
+* multimailhook.commitlist -- This is a new configuration variable.
+  Recipients listed here will receive a separate email for each new
+  commit.  However, if this variable is *not* set, it defaults to the
+  value of multimailhook.mailinglist.  Therefore, if you *don't* want
+  the members of multimailhook.mailinglist to receive one email per
+  commit, then set this value to the empty string:
+
+      git config multimailhook.commitlist ''
+
+* multimailhook.emailprefix -- If this value is not set, then the
+  subjects of generated emails are prefixed with the short name of the
+  repository enclosed in square brackets; e.g., "[myrepo]".
+  post-receive-email defaults to prefix "[SCM]" if this option is not
+  set.  So if you were using the old default and want to retain it
+  (for example, to avoid having to change your email filters), set
+  this variable explicitly to the old value:
+
+      git config multimailhook.emailprefix "[SCM]"
+
+* The "multimailhook.showrev" configuration option is not supported.
+  Its main use is obsoleted by the one-email-per-commit feature of
+  git-multimail.
+
+
+Other differences
+=================
+
+This section describes other differences in the behavior of
+git-multimail vs. post-receive-email.  For full details, please refer
+to the main README file:
+
+* One email per commit.  For each reference change, the script first
+  outputs one email summarizing the reference change (including
+  one-line summaries of the new commits), then it outputs a separate
+  email for each new commit that was introduced, including patches.
+  These one-email-per-commit emails go to the addresses listed in
+  multimailhook.commitlist.  post-receive-email sends only one email
+  for each *reference* that is changed, no matter how many commits
+  were added to the reference.
+
+* Better algorithm for detecting new commits.  post-receive-email
+  processes one reference change at a time, which causes it to fail to
+  describe new commits that were included in multiple branches.  For
+  example, if a single push adds the "*" commits in the diagram below,
+  then post-receive-email would never include the details of the two
+  commits that are common to "master" and "branch" in its
+  notifications.
+
+      o---o---o---*---*---*    <-- master
+                       \
+                        *---*  <-- branch
+
+  git-multimail analyzes all reference modifications to determine
+  which commits were not present before the change, therefore avoiding
+  that error.
+
+* In reference change emails, git-multimail tells which commits have
+  been added to the reference vs. are entirely new to the repository,
+  and which commits that have been omitted from the reference
+  vs. entirely discarded from the repository.
+
+* The environment in which Git is running can be configured via an
+  "Environment" abstraction.
+
+* Built-in support for Gitolite-managed repositories.
+
+* Instead of using full SHA1 object names in emails, git-multimail
+  mostly uses abbreviated SHA1s, plus one-line log message summaries
+  where appropriate.
+
+* In the schematic diagrams that explain non-fast-forward commits,
+  git-multimail shows the names of the branches involved.
+
+* The emails generated by git-multimail include the name of the Git
+  repository that was modified; this is convenient for recipients who
+  are monitoring multiple repositories.
+
+* git-multimail allows the email "From" addresses to be configured.
+
+* The recipients lists (multimailhook.mailinglist,
+  multimailhook.refchangelist, multimailhook.announcelist, and
+  multimailhook.commitlist) can be comma-separated values and/or
+  multivalued settings in the config file; e.g.,
+
+      [multimailhook]
+              mailinglist = mr.brown@example.com, mr.black@example.com
+              announcelist = Him <him@example.com>
+              announcelist = Jim <jim@example.com>
+              announcelist = pop@example.com
+
+  This might make it easier to maintain short recipients lists without
+  requiring full-fledged mailing list software.
+
+* By default, git-multimail sets email "Reply-To" headers to reply to
+  the pusher (for reference updates) and to the author (for commit
+  notifications).  By default, the pusher's email address is
+  constructed by appending "multimailhook.emaildomain" to the pusher's
+  username.
+
+* The generated emails contain a configurable footer.  By default, it
+  lists the name of the administrator who should be contacted to
+  unsubscribe from notification emails.
+
+* New option multimailhook.emailmaxlinelength to limit the length of
+  lines in the main part of the email body.  The default limit is 500
+  characters.
+
+* New option multimailhook.emailstrictutf8 to ensure that the main
+  part of the email body is valid UTF-8.  Invalid characters are
+  turned into the Unicode replacement character, U+FFFD.  By default
+  this option is turned on.
+
+* Written in Python.  Easier to add new features.

+"""Generate notification emails for pushes to a git repository.
+
+This hook sends emails describing changes introduced by pushes to a
+git repository.  For each reference that was changed, it emits one
+ReferenceChange email summarizing how the reference was changed,
+followed by one Revision email for each new commit that was introduced
+by the reference change.
+
+Each commit is announced in exactly one Revision email.  If the same
+commit is merged into another branch in the same or a later push, then
+the ReferenceChange email will list the commit's SHA1 and its one-line
+summary, but no new Revision email will be generated.
+
+This script is designed to be used as a "post-receive" hook in a git
+repository (see githooks(5)).  It can also be used as an "update"
+script, but this usage is not completely reliable and is deprecated.
+
+To help with debugging, this script accepts a --stdout option, which
+causes the emails to be written to standard output rather than sent
+using sendmail.

+
+    * what users want to be informed about various types of changes.

+
+            Return a short name for the repository, for display
+            purposes.
+

+
+            Return the absolute path to the Git repository.
+
+        get_emailprefix()
+
+            Return a string that will be prefixed to every email's

+

+
+            Return the email address of the person who pushed the
+            changes.  The value should be a single RFC 2822 email
+            address as a string; e.g., "Joe User <user@example.com>"
+            if available, otherwise "user@example.com".  If set, the

+
+            Return the 'From' email address used in the email 'From:'
+            headers.  (May be a full RFC 2822 email address like 'Joe
+            User <user@example.com>'.)
+
+        get_administrator()
+
+            Return the name and/or email of the repository
+            administrator.  This value is used in the footer as the

+            notification list should be sent.  Ideally, it should
+            include a valid email address.

+            None to omit the "Reply-To" header.

+
+        git rev-list change.old..change.new
+
+    or removed from a *branch*:
+

+    class is to figure out these things, and to make sure that new
+    commits are only detailed once even if they were added to multiple
+    references.
+
+    The first step is to determine the "other" references--those
+    unaffected by the current push.  They are computed by
+    Push._compute_other_ref_sha1s() by listing all references then
+    removing any affected by this push.
+
+    The commits contained in the repository before this push were
+
+        git rev-list other1 other2 other3 ... change1.old change2.old ...
+
+    Where "changeN.old" is the old value of one of the references
+    affected by this push.
+
+    The commits contained in the repository after this push are
+
+        git rev-list other1 other2 other3 ... change1.new change2.new ...
+
+    The commits added by this push are the difference between these
+    two sets, which can be written
+
+        git rev-list \
+            ^other1 ^other2 ... \
+            ^change1.old ^change2.old ... \
+            change1.new change2.new ...
+
+    The commits removed by this push can be computed by
+
+        git rev-list \
+            ^other1 ^other2 ... \
+            ^change1.new ^change2.new ... \
+            change1.old change2.old ...

+"""Example post-receive hook based on git-multimail.
+
+This script is a simple example of a post-receive hook implemented
+using git_multimail.py as a Python module.  It is intended to be
+customized before use; see the comments in the script to help you get
+started.
+
+It is possible to use git_multimail.py itself as a post-receive or
+update hook, configured via git config settings and/or command-line
+parameters.  But for more flexibility, it can also be imported as a
+Python module by a custom post-receive script as done here.  The
+latter has the following advantages:
+
+* The tool's behavior can be customized using arbitrary Python code,
+  without having to edit git_multimail.py.
+
+* Configuration settings can be read from other sources; for example,
+  user names and email addresses could be read from LDAP or from a
+  database.  Or the settings can even be hardcoded in the importing
+  Python script, if this is preferred.
+
+This script is a very basic example of how to use git_multimail.py as
+a module.  The comments below explain some of the points at which the
+script's behavior could be changed or customized.

+# argument is optional:
+#mailer = git_multimail.SendMailer(

+#    #     smtpserver='mail.example.com:25'
+#    smtpserver='mail.example.com',

+USAGE: git mw preview [--remote|-r <remote name>] [--autoload|-a]
+                      [--output|-o <output filename>] [--verbose|-v]
+                      <blob> | <filename>
+
+DESCRIPTION:
+Preview is an utiliy to preview local content of a mediawiki repo as if it was
+pushed on the remote.
+
+For that, preview searches for the remote name of the current branch's
+upstream if --remote is not set. If that remote is not found or if it
+is not a mediawiki, it lists all mediawiki remotes configured and asks
+you to replay your command with the --remote option set properly.
+
+Then, it searches for a file named 'filename'. If it's not found in
+the current dir, it will assume it's a blob.
+
+The content retrieved in the file (or in the blob) will then be parsed
+by the remote mediawiki and combined with a template retrieved from
+the mediawiki.
+
+Finally, preview will save the HTML result in a file. and autoload it
+in your default web browser if the option --autoload is present.
+
+OPTIONS:
+    -r <remote name>, --remote <remote name>
+        If the remote is a mediawiki, the template and the parse engine
+        used for the preview will be those of that remote.
+        If not, a list of valid remotes will be shown.
+
+    -a, --autoload
+        Try to load the HTML output in a new tab (or new window) of your
+        default web browser.
+
+    -o <output filename>, --output <output filename>
+        Change the HTML output filename. Default filename is based on the
+        input filename with its extension replaced by '.html'.
+
+    -v, --verbose
+        Show more information on what's going on under the hood.

+    # Overview of CVS revision numbers:
+    #
+    # General CVS numbering scheme:
+    #   - Basic mainline branch numbers: "1.1", "1.2", "1.3", etc.
+    #   - Result of "cvs checkin -r" (possible, but not really
+    #     recommended): "2.1", "2.2", etc
+    #   - Branch tag: "1.2.0.n", where "1.2" is revision it was branched
+    #     from, "0" is a magic placeholder that identifies it as a
+    #     branch tag instead of a version tag, and n is 2 times the
+    #     branch number off of "1.2", starting with "2".
+    #   - Version on a branch: "1.2.n.x", where "1.2" is branch-from, "n"
+    #     is branch number off of "1.2" (like n above), and "x" is
+    #     the version number on the branch.
+    #   - Branches can branch off of branches: "1.3.2.7.4.1" (even number
+    #     of components).
+    #   - Odd "n"s are used by "vendor branches" that result
+    #     from "cvs import".  Vendor branches have additional
+    #     strangeness in the sense that the main rcs "head" of the main
+    #     branch will (temporarily until first normal commit) point
+    #     to the version on the vendor branch, rather than the actual
+    #     main branch.  (FUTURE: This may provide an opportunity
+    #     to use "strange" revision numbers for fast-forward-merged
+    #     branch tip when CVS client is asking for the main branch.)
+    #
+    # git-cvsserver CVS-compatible special numbering schemes:
+    #   - Currently git-cvsserver only tries to be identical to CVS for
+    #     simple "1.x" numbers on the "main" branch (as identified
+    #     by the module name that was originally cvs checkout'ed).
+    #   - The database only stores the "x" part, for historical reasons.
+    #     But most of the rest of the cvsserver preserves
+    #     and thinks using the full revision number.
+    #   - To handle non-linear history, it uses a version of the form
+    #     "2.1.1.2000.b.b.b."..., where the 2.1.1.2000 is to help uniquely
+    #     identify this as a special revision number, and there are
+    #     20 b's that together encode the sha1 git commit from which
+    #     this version of this file originated.  Each b is
+    #     the numerical value of the corresponding byte plus
+    #     100.
+    #      - "plus 100" avoids "0"s, and also reduces the
+    #        likelihood of a collision in the case that someone someday
+    #        writes an import tool that tries to preserve original
+    #        CVS revision numbers, and the original CVS data had done
+    #        lots of branches off of branches and other strangeness to
+    #        end up with a real version number that just happens to look
+    #        like this special revision number form.  Also, if needed
+    #        there are several ways to extend/identify alternative encodings
+    #        within the "2.1.1.2000" part if necessary.
+    #      - Unlike real CVS revisions, you can't really reconstruct what
+    #        relation a revision of this form has to other revisions.

+=item credential( CREDENTIAL_HASHREF, CODE )
+
+Executes C<git credential> for a given set of credentials and specified
+operation.  In both forms C<CREDENTIAL_HASHREF> needs to be a reference to
+a hash which stores credentials.  Under certain conditions the hash can
+change.
+
+In the first form, C<OPERATION> can be C<'fill'>, C<'approve'> or C<'reject'>,
+and function will execute corresponding C<git credential> sub-command.  If
+it's omitted C<'fill'> is assumed.  In case of C<'fill'> the values stored in
+C<CREDENTIAL_HASHREF> will be changed to the ones returned by the C<git
+credential fill> command.  The usual usage would look something like:
+
+	my %cred = (
+		'protocol' => 'https',
+		'host' => 'example.com',
+		'username' => 'bob'
+	);
+	Git::credential \%cred;

+		Git::credential \%cred, 'approve';
+		... do more stuff ...
+	} else {
+		Git::credential \%cred, 'reject';
+	}
+
+In the second form, C<CODE> needs to be a reference to a subroutine.  The
+function will execute C<git credential fill> to fill the provided credential
+hash, then call C<CODE> with C<CREDENTIAL_HASHREF> as the sole argument.  If
+C<CODE>'s return value is defined, the function will execute C<git credential
+approve> (if return value yields true) or C<git credential reject> (if return
+value is false).  If the return value is undef, nothing at all is executed;
+this is useful, for example, if the credential could neither be verified nor
+rejected due to an unrelated network error.  The return value is the same as
+what C<CODE> returns.  With this form, the usage might look as follows:
+
+	if (Git::credential {
+		'protocol' => 'https',
+		'host' => 'example.com',
+		'username' => 'bob'
+	}, sub {

+	 *
+	 *   I--------*X       A modified the file, but mainline merge X used
+	 *    \       /        "-s ours", so took the version from I. X is

+	 * Default log from X would produce "I". Without this check,
+	 * --full-history --simplify-merges would produce "I-A-X", showing
+	 * the merge commit X and that it changed A, but not making clear that
+	 * it had just taken the I version. With this check, the topology above

+	 *
+	 * Note that it is possible that the simplification chooses a different
+	 * TREESAME parent from the default, in which case this test doesn't

+	 *
+	 *   I------X         A modified the file, but it was reverted in B,
+	 *    \    /          meaning mainline merge X is TREESAME to both
+	 *    *A-*B           parents.
+	 *
+	 * Default log would produce "I" by following the first parent;
+	 * --full-history --simplify-merges will produce "I-A-B". But this is a
+	 * reasonable result - it presents a logical full history leading from

+# Known issues with git-cvsserver current log output:
+#  - Hard coded "lines: +2 -3" placeholder, instead of real numbers.
+#  - CVS normally does not internally add a blank first line
+#    nor a last line with nothing but a space to log messages.
+#  - The latest cvs 1.12.x server sends +0000 timezone (with some hidden "MT"
+#    tagging in the protocol), and if cvs 1.12.x client sees the MT tags,
+#    it converts to local time zone.  git-cvsserver doesn't do the +0000
+#    or the MT tags...
+#  - The latest 1.12.x releases add a "commitid:" field on to the end of the
+#    "date:" line (after "lines:").  Maybe we could stick git's commit id
+#    in it?  Or does CVS expect a certain number of bits (too few for
+#    a full sha1)?
+#
+# Given the above, expect the following test to break if git-cvsserver's
+# log output is improved.  The test is just to ensure it doesn't
+# accidentally get worse.
