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.
Updating the link to my shell setup: https://github.com/matthewmccullough/dotfiles and https://github.com/matthewmccullough/scripts
I source'd this on my Mac and got gistfile1.sh: line 11: syntax error near unexpected token `{. When I opened the file in TextMate, I noticed the line endings were CRLF (Windows). I saved the file with LF and was able to execute the script. I think this may be very helpful. Thanks. See you at NFJS in Redmond!
