+Git 1.8.1.3 Release Notes
+=========================
+
+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.

+Git 1.8.1.5 Release Notes
+=========================
+
+Fixes since v1.8.1.4
+--------------------
+
+ * Given a string with a multi-byte character that begins with '-' on
+   the command line where an option is expected, the option parser
+   used just one byte of the unknown letter when reporting an error.
+
+ * In v1.8.1, the attribute parser was tightened too restrictive to
+   error out upon seeing an entry that begins with an ! (exclamation),
+   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.

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

+   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

+
+ * 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

+   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

+
+ * 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
+   acccumulate 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 Release Notes
 ========================
 
-Backward compatibility notes
-----------------------------
-
-In the upcoming major release (tentatively called 1.8.2), 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.
+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 decendant of a commit
+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.

+Git v1.8.3 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.  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 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.
+
+ * "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
+
+ * "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/ hierachies 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.
+
+ * Instead of typing four capital letters "HEAD", you can say "@" now,
+   e.g. "git log @".
+
+ * "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.
+
+ * 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 rerferences 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).
+
+ * 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).
+
+ * "git stash save", when your local change turns a tracked file into
+   a directory, has to remove files in that directory in order to
+   revert your working tree to a pristine state.  This will lose
+   untracked files in such a directory, and the command now requires
+   you to "--force" it.
+
+ * 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 maintanance 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.

+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 split at the first whitespace boundary. All characters
+before that whitespace are considered as a whole object name, and are
+parsed as if given to linkgit:git-rev-parse[1]. Characters after that
+whitespace can be accessed using the `%(rest)` atom (see below).
+
+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.
+
+`rest`::
+	The text (if any) found after the first run of whitespace on the
+	input line (i.e., the "rest" of the line).
+
+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
-each object specified on stdin:
+Whereas `--batch-check='%(objectname) %(objecttype)'` would produce:
 
 ------------
-<sha1> SP <type> SP <size> LF
+<sha1> SP <type> LF
 ------------
 
-For both '--batch' and '--batch-check', output of the following form is printed
-for each object specified on stdin that does not exist in the repository:
+If a name is specified on stdin that cannot be resolved to an object in
+the repository, then `cat-file` will ignore any custom format and print:
 
 ------------
 <object> SP missing LF
 ------------
 
+
+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.

+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

 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 $USER! You've successfully authenticated, but I do not"
+printf '%s\n' "provide interactive shell access."
+exit 128
+EOF
+$ chmod +x $HOME/git-shell-commands/no-interactive-login

+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

-#!/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.

+                       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.

+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.

+=item credential( CREDENTIAL_HASHREF [, OPERATION ] )

+=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;
+	if (try_to_authenticate($cred{'username'}, $cred{'password'})) {
+		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 {
+		my $cred = shift;
+		return !!try_to_authenticate($cred->{'username'},

+ * A definition of "relevant" commit that we can use to simplify limited graphs
+ * by eliminating side branches.
+ *
+ * A "relevant" commit is one that is !UNINTERESTING (ie we are including it
+ * in our list), or that is a specified BOTTOM commit. Then after computing
+ * a limited list, during processing we can generally ignore boundary merges
+ * coming from outside the graph, (ie from irrelevant parents), and treat
+ * those merges as if they were single-parent. TREESAME is defined to consider
+ * only relevant parents, if any. If we are TREESAME to our on-graph parents,
+ * we don't care if we were !TREESAME to non-graph parents.
+ *
+ * Treating bottom commits as relevant ensures that a limited graph's
+ * connection to the actual bottom commit is not viewed as a side branch, but
+ * treated as part of the graph. For example:
+ *
+ *   ....Z...A---X---o---o---B
+ *        .     /
+ *         W---Y
+ *
+ * When computing "A..B", the A-X connection is at least as important as
+ * Y-X, despite A being flagged UNINTERESTING.
+ *
+ * And when computing --ancestry-path "A..B", the A-X connection is more
+ * important than Y-X, despite both A and Y being flagged UNINTERESTING.

+	 *
+	 * 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
