Help stop yourself from working with the wrong cobzr branch

[Gary Poster]

Hi.  Francesco Banconi, on the Yellow squad, wanted to keep from doing
work in the wrong cobzr branch.  He came up with the following snippet
to add your cobzr branch to the prompt.  He warns that it is not very
efficient, but works for him.

I thought it was worth sharing beyond the people looking at IRC at that
instant, so here it is.  Enjoy and/or suggest improvements as desired!
