Improved bash prompt for git usage

I've found some interesting gists on github. There are many flavor of a bash prompt showing which branch you're on, and if you have uncommited changes.

I've forked mine here it is:

I'm not sure I'll keep it though, since I'm using it on my virtualbox (with shared folders) and it makes the prompt rather slow. Anyway it's kind of cool, I also have it natively on my mac and I don't have any speed issue.
