"git index-pack --stdin" needs an access to an existing repository,
but "git index-pack file.pack" to generate an .idx file that
corresponds to a packfile does not.

* jk/index-pack-wo-repo-from-stdin:
index-pack: skip collision check when not in repository
t: use nongit() function where applicable
index-pack: complain when --stdin is used outside of a repo
t5000: extract nongit function to test-lib-functions.sh

+Git v2.10.3 Release Notes
+=========================
+
+Fixes since v2.10.2
+-------------------
+
+ * Extract a small helper out of the function that reads the authors
+   script file "git am" internally uses.
+   This by itself is not useful until a second caller appears in the
+   future for "rebase -i" helper.
+
+ * The command-line completion script (in contrib/) learned to
+   complete "git cmd ^mas<HT>" to complete the negative end of
+   reference to "git cmd ^master".
+
+ * "git send-email" attempts to pick up valid e-mails from the
+   trailers, but people in real world write non-addresses there, like
+   "Cc: Stable <add@re.ss> # 4.8+", which broke the output depending
+   on the availability and vintage of Mail::Address perl module.
+
+ * The code that we have used for the past 10+ years to cycle
+   4-element ring buffers turns out to be not quite portable in
+   theoretical world.
+
+ * "git daemon" used fixed-length buffers to turn URL to the
+   repository the client asked for into the server side directory
+   path, using snprintf() to avoid overflowing these buffers, but
+   allowed possibly truncated paths to the directory.  This has been
+   tightened to reject such a request that causes overlong path to be
+   required to serve.
+
+ * Recent update to git-sh-setup (a library of shell functions that
+   are used by our in-tree scripted Porcelain commands) included
+   another shell library git-sh-i18n without specifying where it is,
+   relying on the $PATH.  This has been fixed to be more explicit by
+   prefixing $(git --exec-path) output in front.
+
+ * Fix for a racy false-positive test failure.
+
+ * Portability update and workaround for builds on recent Mac OS X.
+
+ * Update to the test framework made in 2.9 timeframe broke running
+   the tests under valgrind, which has been fixed.
+
+ * Improve the rule to convert "unsigned char [20]" into "struct
+   object_id *" in contrib/coccinelle/
+
+Also contains minor documentation updates and code clean-ups.

+TL;DR: Run update_unicode.sh after the publication of a new Unicode
+standard and commit the resulting unicode_widths.h file.
+
+The long version
+================
+
+The Git source code ships the file unicode_widths.h which contains
+tables of zero and double width Unicode code points, respectively.
+These tables are generated using update_unicode.sh in this directory.
+update_unicode.sh itself uses a third-party tool, uniset, to query two
+Unicode data files for the interesting code points.
+
+On first run, update_unicode.sh clones uniset from Github and builds it.
+This requires a current-ish version of autoconf (2.69 works per December
+2016).
+
+On each run, update_unicode.sh checks whether more recent Unicode data
+files are available from the Unicode consortium, and rebuilds the header
+unicode_widths.h with the new data. The new header can then be
+committed.
