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.
