Below is my setup for my prompts; it's a bit *more* than what you ask for, but
it is hopefully helpful.

It has the following properties:
- put the branch in the right prompt if we're in some directory with 'src' in
  otherwise show nothing (it works for cvs/svn/bzr/git here at least)
- show the return code of the last command in the prompt, but only if it was
  nonzero
- use different colors for different machines/users (I'm using the same .zshrc
  on different machines/users)

Overall, it's a combination of snippets I found in different places; I'm sure
it can be improved, but it works pretty well for me.

Best wishes,
Dirk.
