I think it would actually be a somewhat interesting feature if it
interacted with GIT_PS1_SHOW*. If you use these settings (I personally
use SHOWDIRTYSTATE but not SHOWUNTRACKEDFILES), the prompt hangs while
__git_ps1 runs git-status. It should be possible to run a git-status
process in the background when entering a repository, and displaying
some marker ('??' maybe) in the prompt instead of the dirty-state info
until git-status has finished. That way the user doesn't have his shell
blocked by cding to a big repo.
