From: SZEDER Gábor <szeder@xxxxxxxxxx>
When the environment variable $GIT_PS1_SHOWSTASHSTATE is set
__git_ps1() checks the presence of stashes by running 'git rev-parse
--verify refs/stash'. This command not only checks that the
'refs/stash' ref exists but also, well, verifies that it's a valid
ref.
However, we don't need to be that thorough for the bash prompt. We
can omit that verification and only check whether 'refs/stash' exists
or not. Since 'git pack-refs' never packs 'refs/stash', it's a matter
of checking the existence of a ref file. Perform this check using
only bash builtins to spare the overhead of fork()+exec()ing a git
process.
