completion: Better __git_ps1 support when not in working directory
If .git/HEAD is not readable, __git_ps1 does nothing.
If --is-in-git-dir, __git_ps1 returns " (GIT_DIR!)" as a cautionary
note. The previous behavior would show the branch name (and would
optionally attempt to determine the dirtyState of the directory, which
was impossible because a "git diff" was used).
If --is-in-work-tree, __git_ps1 returns the branch name. Additionally,
if showDirtyState is on, the dirty state is displayed.
