[ANNOUNCE] GIT 1.2.3

The latest maintenance release GIT 1.2.3 is available at the usual places:

	http://www.kernel.org/pub/software/scm/git/

	git-1.2.3.tar.{gz,bz2}			(tarball)
	RPMS/$arch/git-*-1.2.3-1.$arch.rpm	(RPM)

This contains some documentation updates, and a fix for the "empty ident not allowed" problem that bit too many people.

Breaking the tradition, this is _not_ a pure bugfix release, however. It contains backports of the much talked about "reuse data from existing pack" optimization from the master branch.

Hopefully this would help downloading from the kernel.org servers over git native protocol.
