[PATCH] Change git-branch to list branches

Browse Source 
If no argument provided to `git branch`, show available branches and
mark current branch with star.

This is based on patch written by Amos Waterland <apw@rossby.metr.ou.edu>.

[jc: and I changed it to handle subdirectories under refs/heads/ as well.]
