[ANNOUNCE] Git v2.2.2

[Junio C Hamano]

The latest maintenance release Git v2.2.2 is now available at
the usual places.

This backports many fixes that were not in 2.2.1 that have been used
on 'master' for the past few weeks.

The tarballs are found at:

tag and the 'maint' branch that the tag points at:

Git v2.2.2 Release Notes
========================

Fixes since v2.2.1
------------------

 * "git checkout $treeish $path", when $path in the index and the
   working tree already matched what is in $treeish at the $path,
   still overwrote the $path unnecessarily.

 * "git config --get-color" did not parse its command line arguments
   carefully.

 * open() emulated on Windows platforms did not give EISDIR upon
   an attempt to open a directory for writing.

 * A few code paths used abs() when they should have used labs() on
   long integers.

 * "gitweb" used to depend on a behaviour recent CGI.pm deprecated.

 * "git init" (hence "git clone") initialized the per-repository
   configuration file .git/config with x-bit by mistake.

 * Git 2.0 was supposed to make the "simple" mode for the default of
   "git push", but it didn't.

 * "Everyday" document had a broken link.

 * The build procedure did not bother fixing perl and python scripts
   when NO_PERL and NO_PYTHON build-time configuration changed.

 * The code that reads the reflog from the newer to the older entries
   did not handle an entry that crosses a boundary of block it uses to
   read them correctly.

 * "git apply" was described in the documentation to take --ignore-date
   option, which it does not.

 * Traditionally we tried to avoid interpreting date strings given by
   the user as future dates, e.g. GIT_COMMITTER_DATE=2014-12-10 when
   used early November 2014 was taken as "October 12, 2014" because it
   is likely that a date in the future, December 10, is a mistake.
   This heuristics has been loosened to allow people to express future
   dates (most notably, --until=<date> may want to be far in the
   future) and we no longer tiebreak by future-ness of the date when

    (1) ISO-like format is used, and
    (2) the string can make sense interpreted as both y-m-d and y-d-m.

   Git may still have to use the heuristics to tiebreak between dd/mm/yy
   and mm/dd/yy, though.

 * The code to abbreviate an object name to its short unique prefix
   has been optimized when no abbreviation was requested.

 * "git add --ignore-errors ..." did not ignore an error to
   give a file that did not exist.

 * Git did not correctly read an overlong refname from a packed refs
   file.

Also contains typofixes, documentation updates and trivial code clean-ups.
