Seems interesting to me. The big thing for me is that we shouldn't be versioning
it as a '.' file. Specifically it should be called
'contrib/bash/bzrbashprompt.sh' and people can rename it to .bzrbashprompt.sh
when they install it. Otherwise it won't show up in a plain 'ls' of that directory.

It seems like it works here, so I think it is worth merging with that trivial
change.
