Matthew, is this zsh friendly as well?

I have a better total-config setup for you that includes my latest ZSH derivations. It is at https://github.com/matthewmccullough/MatthewsShellConfig

Hey, thank you for posting that. I found a different one the internet a long time ago. Posting a comment here because it's related.

Glad to have provided it and also a nod to @halbtuerke who started the bulk of this code.

This is great. Exactly what I was looking for. Really the only thing I changed (other than the prompt itself) was to clear the state variable every run. It was always saying my repo was dirty once it had been dirty. I actually just put an else and made a blue "C" for clean working state.

Update: Added number of commits ahead/behind.

Thrills me to hear of forking. I'm pulling in your version now!
