The latest maintenance release Git v2.14.2 is now available at the
usual places.  In addition to the cvsserver related fixes that
appear in 2.10.5, 2.11.4, 2.12.5 and 2.13.6 announced separately,
this also includes various fixes that were merged already to the
'master' branch.

The tarballs are found at:

Git v2.14.2 Release Notes
=========================

Fixes since v2.14.1
-------------------

 * Because recent Git for Windows do come with a real msgfmt, the
   build procedure for git-gui has been updated to use it instead of a
   hand-rolled substitute.

 * "%C(color name)" in the pretty print format always produced ANSI
   color escape codes, which was an early design mistake.  They now
   honor the configuration (e.g. "color.ui = never") and also tty-ness
   of the output medium.

 * The http.{sslkey,sslCert} configuration variables are to be
   interpreted as a pathname that honors "~[username]/" prefix, but
   weren't, which has been fixed.

 * Numerous bugs in walking of reflogs via "log -g" and friends have
   been fixed.

 * "git commit" when seeing an totally empty message said "you did not
   edit the message", which is clearly wrong.  The message has been
   corrected.

 * When a directory is not readable, "gitweb" fails to build the
   project list.  Work this around by skipping such a directory.

 * A recently added test for the "credential-cache" helper revealed
   that EOF detection done around the time the connection to the cache
   daemon is torn down were flaky.  This was fixed by reacting to
   ECONNRESET and behaving as if we got an EOF.

 * Some versions of GnuPG fail to kill gpg-agent it auto-spawned
   and such a left-over agent can interfere with a test.  Work it
   around by attempting to kill one before starting a new test.

 * "git log --tag=no-such-tag" showed log starting from HEAD, which
   has been fixed---it now shows nothing.

 * The "tag.pager" configuration variable was useless for those who
   actually create tag objects, as it interfered with the use of an
   editor.  A new mechanism has been introduced for commands to enable
   pager depending on what operation is being carried out to fix this,
   and then "git tag -l" is made to run pager by default.

 * "git push --recurse-submodules $there HEAD:$target" was not
   propagated down to the submodules, but now it is.

 * Commands like "git rebase" accepted the --rerere-autoupdate option
   from the command line, but did not always use it.  This has been
   fixed.

 * "git clone --recurse-submodules --quiet" did not pass the quiet
   option down to submodules.

 * "git am -s" has been taught that some input may end with a trailer
   block that is not Signed-off-by: and it should refrain from adding
   an extra blank line before adding a new sign-off in such a case.

 * "git svn" used with "--localtime" option did not compute the tz
   offset for the timestamp in question and instead always used the
   current time, which has been corrected.

 * Memory leaks in a few error codepaths have been plugged.

 * bash 4.4 or newer gave a warning on NUL byte in command
   substitution done in "git stash"; this has been squelched.

 * "git grep -L" and "git grep --quiet -L" reported different exit
   codes; this has been corrected.

 * When handshake with a subprocess filter notices that the process
   asked for an unknown capability, Git did not report what program
   the offending subprocess was running.  This has been corrected.

 * "git apply" that is used as a better "patch -p1" failed to apply a
   taken from a file with CRLF line endings to a file with CRLF line
   endings.  The root cause was because it misused convert_to_git()
   that tried to do "safe-crlf" processing by looking at the index
   entry at the same path, which is a nonsense---in that mode, "apply"
   is not working on the data in (or derived from) the index at all.
   This has been fixed.

 * Killing "git merge --edit" before the editor returns control left
   the repository in a state with MERGE_MSG but without MERGE_HEAD,
   which incorrectly tells the subsequent "git commit" that there was
   a squash merge in progress.  This has been fixed.

 * "git archive" did not work well with pathspecs and the
   export-ignore attribute.

 * "git cvsserver" no longer is invoked by "git shell" by default,
   as it is old and largely unmaintained.

 * Various Perl scripts did not use safe_pipe_capture() instead of
   backticks, leaving them susceptible to end-user input.  They have
   been corrected.

Also contains various documentation updates and code clean-ups.

unsafe constructs in "git cvsserver", and to Jeff King at GitHub for
finding and fixing instances of the same issue in other scripts.
