What's in git.git (stable)

I should probably do a 1.5.4.4 shortly from 'maint' to flush accumulated fixes. There is nothing major, but send-email regression fix deserves to be delibered sooner to the end users.

On the 'master', we briefly had a faulty receive-pack to cause a small pushes to fail, but that glitch has been reverted. Also fixed was a git-describe not quite working when your tags are packed (e.g. after git-gc).
