This line doesn't quite work yet. I haven't had time to fix it.
At the moment, this is a regression, because it shows (bzr) even when you are not a a bzr directory.

This is because $bzr_root can never return a non zero exit status, because it is not a function.

I don't know quite enough bash to fix this, and don't have time to learn at the moment.
