Documentation: move RelNotes into a directory of their own

There are 108 of them already.  That's a bit more than one third of
all the files in the Documentation directory already, and still growing.

+Git v1.7.0 Release Notes
+========================
+
+Notes on behaviour change
+-------------------------
+
+ * "git push" into a branch that is currently checked out (i.e. pointed at by
+   HEAD in a repository that is not bare) is refused by default.
+
+   Similarly, "git push $there :$killed" to delete the branch $killed
+   in a remote repository $there, when $killed branch is the current
+   branch pointed at by its HEAD, will be refused by default.
+
+   Setting the configuration variables receive.denyCurrentBranch and
+   receive.denyDeleteCurrent to 'ignore' in the receiving repository
+   can be used to override these safety features.
+
+ * "git send-email" does not make deep threads by default when sending a
+   patch series with more than two messages.  All messages will be sent
+   as a reply to the first message, i.e. cover letter.
+
+   It has been possible already to configure send-email to send "shallow thread"
+   by setting sendemail.chainreplyto configuration variable to false.  The
+   only thing this release does is to change the default when you haven't
+   configured that variable.
+
+ * "git status" is not "git commit --dry-run" anymore.  This change does
+   not affect you if you run the command without argument.
+
+ * "git diff" traditionally treated various "ignore whitespace" options
+   only as a way to filter the patch output.  "git diff --exit-code -b"
+   exited with non-zero status even if all changes were about changing the
+   amount of whitespace and nothing else;  and "git diff -b" showed the
+   "diff --git" header line for such a change without patch text.
+
+   In this release, the "ignore whitespaces" options affect the semantics
+   of the diff operation.  A change that does not affect anything but
+   whitespaces is reported with zero exit status when run with
+   --exit-code, and there is no "diff --git" header for such a change.
+
+ * External diff and textconv helpers are now executed using the shell.
+   This makes them consistent with other programs executed by git, and
+   allows you to pass command-line parameters to the helpers. Any helper
+   paths containing spaces or other metacharacters now need to be
+   shell-quoted.  The affected helpers are GIT_EXTERNAL_DIFF in the
+   environment, and diff.*.command and diff.*.textconv in the config
+   file.
+
+ * The --max-pack-size argument to 'git repack', 'git pack-objects', and
+   'git fast-import' was assuming the provided size to be expressed in MiB,
+   unlike the corresponding config variable and other similar options accepting
+   a size value.  It is now expecting a size expressed in bytes, with a possible
+   unit suffix of 'k', 'm', or 'g'.
+
+Updates since v1.6.6
+--------------------
+
+(subsystems)
+
+ * "git fast-import" updates; adds "option" and "feature" to detect the
+   mismatch between fast-import and the frontends that produce the input
+   stream.
+
+ * "git svn" support of subversion "merge tickets" and miscellaneous fixes.
+
+ * "gitk" and "git gui" translation updates.
+
+ * "gitweb" updates (code clean-up, load checking etc.)
+
+(portability)
+
+ * Some more MSVC portability patches for msysgit port.
+
+ * Minimum Pthreads emulation for msysgit port.
+
+(performance)
+
+ * More performance improvement patches for msysgit port.
+
+(usability, bells and whistles)
+
+ * More commands learned "--quiet" and "--[no-]progress" options.
+
+ * Various commands given by the end user (e.g. diff.type.textconv,
+   and GIT_EDITOR) can be specified with command line arguments.  E.g. it
+   is now possible to say "[diff "utf8doc"] textconv = nkf -w".
+
+ * "sparse checkout" feature allows only part of the work tree to be
+   checked out.
+
+ * HTTP transfer can use authentication scheme other than basic
+   (i.e./e.g. digest).
+
+ * Switching from a version of superproject that used to have a submodule
+   to another version of superproject that no longer has it did not remove
+   the submodule directory when it should (namely, when you are not
+   interested in the submodule at all and didn't clone/checkout).
+
+ * A new attribute conflict-marker-size can be used to change the size of
+   the conflict markers from the default 7; this is useful when tracked
+   contents (e.g. git-merge documentation) have strings that resemble the
+   conflict markers.
+
+ * A new syntax "<branch>@{upstream}" can be used on the command line to
+   substitute the name of the "upstream" of the branch.  Missing branch
+   defaults to the current branch, so "git fetch && git merge @{upstream}"
+   will be equivalent to "git pull".
+
+ * "git am --resolved" has a synonym "git am --continue".
+
+ * "git branch --set-upstream" can be used to update the (surprise!) upstream,
+   i.e. where the branch is supposed to pull and merge from (or rebase onto).
+
+ * "git checkout A...B" is a way to detach HEAD at the merge base between
+   A and B.
+
+ * "git checkout -m path" to reset the work tree file back into the
+   conflicted state works even when you already ran "git add path" and
+   resolved the conflicts.
+
+ * "git commit --date='<date>'" can be used to override the author date
+   just like "git commit --author='<name> <email>'" can be used to
+   override the author identity.
+
+ * "git commit --no-status" can be used to omit the listing of the index
+   and the work tree status in the editor used to prepare the log message.
+
+ * "git commit" warns a bit more aggressively until you configure user.email,
+   whose default value almost always is not (and fundamentally cannot be)
+   what you want.
+
+ * "git difftool" has been extended to make it easier to integrate it
+   with gitk.
+
+ * "git fetch --all" can now be used in place of "git remote update".
+
+ * "git grep" does not rely on external grep anymore.  It can use more than
+   one thread to accelerate the operation.
+
+ * "git grep" learned "--quiet" option.
+
+ * "git log" and friends learned "--glob=heads/*" syntax that is a more
+   flexible way to complement "--branches/--tags/--remotes".
+
+ * "git merge" learned to pass options specific to strategy-backends.  E.g.
+
+    - "git merge -Xsubtree=path/to/directory" can be used to tell the subtree
+      strategy how much to shift the trees explicitly.
+
+    - "git merge -Xtheirs" can be used to auto-merge as much as possible,
+      while discarding your own changes and taking merged version in
+      conflicted regions.
+
+ * "git push" learned "git push origin --delete branch", a syntactic sugar
+   for "git push origin :branch".
+
+ * "git push" learned "git push --set-upstream origin forker:forkee" that
+   lets you configure your "forker" branch to later pull from "forkee"
+   branch at "origin".
+
+ * "git rebase --onto A...B" means the history is replayed on top of the
+   merge base between A and B.
+
+ * "git rebase -i" learned new action "fixup" that squashes the change
+   but does not affect existing log message.
+
+ * "git rebase -i" also learned --autosquash option that is useful
+   together with the new "fixup" action.
+
+ * "git remote" learned set-url subcommand that updates (surprise!) url
+   for an existing remote nickname.
+
+ * "git rerere" learned "forget path" subcommand.  Together with "git
+   checkout -m path" it will be useful when you recorded a wrong
+   resolution.
+
+ * Use of "git reset --merge" has become easier when resetting away a
+   conflicted mess left in the work tree.
+
+ * "git rerere" had rerere.autoupdate configuration but there was no way
+   to countermand it from the command line; --no-rerere-autoupdate option
+   given to "merge", "revert", etc. fixes this.
+
+ * "git status" learned "-s(hort)" output format.
+
+(developers)
+
+ * The infrastructure to build foreign SCM interface has been updated.
+
+ * Many more commands are now built-in.
+
+ * THREADED_DELTA_SEARCH is no more.  If you build with threads, delta
+   compression will always take advantage of it.
+
+Fixes since v1.6.6
+------------------
+
+All of the fixes in v1.6.6.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git branch -d branch" used to refuse deleting the branch even when
+   the branch is fully merged to its upstream branch if it is not merged
+   to the current branch.  It now deletes it in such a case.
+
+ * "filter-branch" command incorrectly said --prune-empty and --filter-commit
+   were incompatible; the latter should be read as --commit-filter.
+
+ * When using "git status" or asking "git diff" to compare the work tree
+   with something, they used to consider that a checked-out submodule with
+   uncommitted changes is not modified; this could cause people to forget
+   committing these changes in the submodule before committing in the
+   superproject. They now consider such a change as a modification and
+   "git diff" will append a "-dirty" to the work tree side when generating
+   patch output or when used with the --submodule option.
