It's tagged and pushed out to both kernel.org and repo.or.cz.  Thanks, Nico.

I won't be doing my usual full release engineering on this one, but I did:

 - repack a copy of git.git to use pack idx version #2 for trial.

	Hint.  A handy way to tell which version of packfile you have is
	to run this:

	$ od -c .git/objects/pack/pack-$your_pack_id.idx | head -n 1
        
        If the output begins with "377 t 0 c", you have pack idx version
        #2.

 - check "git log" from v1.4.4.4 (fails) and v1.4.4.5 (reads ok)

 - repack this copy with "git repack" from 1.4.4.5.  This produced a
   repository usable by v1.4.4.4.

I also updated /pub/scm/git/git.git/config at kernel.org to use

	[pack]
        	indexVersion = 1

for now.  The repository is also repacked with pack idx version #1.
