* "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, one of the changes has to be lost in such a case, but it
+ tells the user what happened and refrains from overwriting the copy
+ in the working tree.
+
+ * 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.
codepaths, and setting permission bits to 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.
+
Also contains minor documentation updates and code clean-ups.
track are contained in this release (see release notes to them for
details).
+ * Fix 1.8.1.x regression that stopped matching "dir" (without
+ trailing slash) to a directory "dir".
+ (merge efa5f82 jc/directory-attrs-regression-fix later to maint-1.8.1).
+
+ * "git apply --whitespace=fix" was not prepared to see a line getting
+ longer after fixing whitespaces (e.g. tab-in-indent aka Python).
+ (merge 329b26e jc/apply-ws-fix-tab-in-indent later to maint-1.8.1).
+
+ * The prompt string generator (in contrib/completion/) did not notice
+ when we are in a middle of a "git revert" session.
+ (merge 3ee4452 rr/prompt-revert-head later to maint).
+
+ * "submodule summary --summary-limit" option did not support
+ "--option=value" form.
+ (merge 862ae6c rs/submodule-summary-limit later to maint).
+
* "index-pack --fix-thin" used uninitialize value to compute delta
depths of objects it appends to the resulting pack.
(merge 57165db jk/index-pack-correct-depth-fix later to maint).
* 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.
- (merge 2092678 kb/name-hash later to maint).
* Annotated tags outside refs/tags/ hierarchy were not advertised
correctly to the ls-remote and fetch with recent version of Git.
- (merge c29c46f jk/fully-peeled-packed-ref later to maint).
* Recent optimization broke shallow clones.
(merge f59de5d jk/peel-ref later to maint).
* "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and
instead the parser kept reading beyond the end of the string.
- (merge f612a67 lf/setup-prefix-pathspec later to maint).
* "git tag -f <tag>" always said "Updated tag '<tag>'" even when
creating a new tag (i.e. not overwriting nor updating).
- (merge 3ae851e ph/tag-force-no-warn-on-creation later to maint).
* "git p4" did not behave well when the path to the root of the P4
client was not its real path.
* "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.
- (merge bd54cf1 jk/empty-archive later to maint).
* 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.
- (merge 6cd3c05 ks/rfc2047-one-char-at-a-time later to maint).
* 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.
- (merge 2cd83d1 jk/alias-in-bare later to maint).
* In "git reflog expire", REACHABLE bit was not cleared from the
correct objects.
"--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.
- (merge 46e1d6e jc/describe later to maint).
* Clarify in the documentation "what" gets pushed to "where" when the
command line to "git push" does not say these explicitly.
* 'git commit -m "$msg"' used to add an extra newline even when
$msg already ended with one.
- (merge 46fbf75 bc/commit-complete-lines-given-via-m-option later to maint).
* 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.
- (merge 0174eea mg/gpg-interface-using-status later to maint).
* Some platforms and users spell UTF-8 differently; retry with the
most official "UTF-8" when the system does not understand the
