Feature request #2016: Update to Git 1.7.12.4

On the site and everywhere I use Git:

The latest maintenance release Git v1.7.12.4 is now available at
the usual places.

The release tarballs are found at:

    http://code.google.com/p/git-core/downloads/list

and their SHA-1 checksums are:

e7eb697fc12887138e44ae100165c620a1210e81  git-1.7.12.4.tar.gz
1d4ce5c8fabbf576d611effcce2f87089da1bb89  git-htmldocs-1.7.12.4.tar.gz
1f853aa40c4518a4fad829f255c96d6e21659e93  git-manpages-1.7.12.4.tar.gz

Also the following public repositories all have a copy of the v1.7.12.4
tag and the maint branch that the tag points at:

  url = https://code.google.com/p/git-core/

Git 1.7.12.4 Release Notes
==========================

Fixes since v1.7.12.3
---------------------

 * "git fetch" over the dumb-http revision walker could segfault when
   curl's multi interface was used.

 * It was possible to give specific paths for "asciidoc" and other
   tools in the documentation toolchain, but not for "xmlto".

 * "gitweb" did not give the correct committer timezone in its feed
   output due to a typo.

 * The "-Xours" (and similarly -Xtheirs) backend option to "git
   merge -s recursive" was ignored for binary files.  Now it is
   honored.

 * The "binary" synthetic attribute made "diff" to treat the path as
   binary, but not "merge".

Also contains many documentation updates.
