complete-git-branches

# This adds tab completion of git branch names (including remotes) to several
# git-related bash aliases I have set up:
#
#   co  git checkout
#   gb  git branch
#   gm  git merge
#
#
# Bugs:
#
# When I tab-complete the empty string I get a directory listing plus the
# remotes. I would prefer to just have all branches.
