* "git blame" learned to produce the progress eye-candy when it takes
too much time before emitting the first line of the result.
- (merge aba37f4 ea/blame-progress later to maint).
* "git grep" can now be configured (or told from the command line)
how many threads to use when searching in the working tree files.
- (merge 89f09dd vl/grep-configurable-threads later to maint).

+ * Some "git notes" operations, e.g. "git log --notes=<note>", should
+ be able to read notes from any tree-ish that is shaped like a notes
+ tree, but the notes infrastructure required that the argument must
+ be a ref under refs/notes/. Loosen it to require a valid ref only
+ when the operation would update the notes (in which case we must
+ have a place to store the updated notes tree, iow, a ref).
+
+ * "git grep" by default does not fall back to its "--no-index"
+ behaviour outside a directory under Git's control (otherwise the
+ user may by mistake end up running a huge recursive search); with a
+ new configuration (set in $HOME/.gitconfig--by definition this
+ cannot be set in the config file per project), this safety can be
+ disabled.
Performance, Internal Implementation, Development Support etc.
* A slight update to the Makefile to mark "phoney" targets
as such correctly.
+ * In-core storage of the reverse index for .pack files (which lets
+ you go from a pack offset to an object name) has been streamlined.
+
+ * d95138e6 (setup: set env $GIT_WORK_TREE when work tree is set, like
+ $GIT_DIR, 2015-06-26) attempted to work around a glitch in alias
+ handling by overwriting GIT_WORK_TREE environment variable to
+ affect subprocesses when set_git_work_tree() gets called, which
+ resulted in a rather unpleasant regression to "clone" and "init".
+ Try to address the same issue by always restoring the environment
+ and respawning the real underlying command when handling alias.

Also contains various documentation updates and code clean-ups.
interfering when they tried to use a different working tree without
setting GIT_WORK_TREE environment themselves.

+
+ * The "exclude_list" structure has the usual "alloc, nr" pair of
+ fields to be used by ALLOC_GROW(), but clear_exclude_list() forgot
+ to reset 'alloc' to 0 when it cleared 'nr' to discard the managed
+ array.
+ (merge 2653a8c nd/dir-exclude-cleanup later to maint).
+
+ * Paths that have been told the index about with "add -N" are not
+ quite yet in the index, but a few commands behaved as if they
+ already are in a harmful way.
+ (merge 4d55200 nd/ita-cleanup later to maint).
+
+ * "git send-email" was confused by escaped quotes stored in the alias
+ files saved by "mutt", which has been corrected.
+ (merge 2c510f2 ew/send-email-mutt-alias-fix later to maint).
+
+ * A few unportable C construct have been spotted by clang compiler
+ and have been fixed.
+ (merge a0df2e5 jk/clang-pedantic later to maint).
+
+ * The documentation has been updated to hint the connection between
+ the '--signoff' option and DCO.
+ (merge b2c150d dw/signoff-doc later to maint).
+
+ * "git reflog" incorrectly assumed that all objects that used to be
+ at the tip of a ref must be commits, which caused it to segfault.
+ (merge aecad37 dk/reflog-walk-with-non-commit later to maint).
+
+ * The ignore mechanism saw a few regressions around untracked file
+ listing and sparse checkout selection areas in 2.7.0; the change
+ that is responsible for the regression has been reverted.
+ (merge 8c72236 nd/exclusion-regression-fix later to maint).
+
+ * Some codepaths used fopen(3) when opening a fixed path in $GIT_DIR
+ (e.g. COMMIT_EDITMSG) that is meant to be left after the command is
+ done. This however did not work well if the repository is set to
+ be shared with core.sharedRepository and the umask of the previous
+ user is tighter. They have been made to work better by calling
+ unlink(2) and retrying after fopen(3) fails with EPERM.
+ (merge ea56518 js/fopen-harder later to maint).
+
+ * Asking gitweb for a nonexistent commit left a warning in the server
+ log.
+
+ Somebody may want to follow this up with an additional test, perhaps?
+ IIRC, we do test that no Perl warnings are given to the server log,
+ so this should have been caught if our test coverage were good.
