[PATCH v3] Add bare repository indicator for __git_ps1

[Marius Storm-Olsen <git@storm-olsen.com>]

Prefixes the branch name with "BARE:" if you're in a
bare repository.

 Well there you go. That's what you get for not testing your
 patch after a rebase.. another version. ;-)

 Next had progressed into handling the --inside-git-dir case,
 and would replace branch name with "GIT_DIR!". Now, that's
 not so useful when that GIT_DIR! is a bare repository, so
 this version will prefix the branch name with "BARE:"
 instead.
