two things.
1. Would recommend against 'function'. not as portable.
2. I use this for my parse_git_branch

__git_ps1() {
    ref=$(git symbolic-ref -q HEAD 2> /dev/null) || return
    printf "${1:- (%s)}" "${ref#refs/heads/}"
}

then I use __git_ps1 in my PS1. This has the added benefit that if I use git-bashcompletion, it provides __git_ps1 which will override my declaration, and gives a more robust ps1 (handles some edge cases).

Cactus, thanks for the notes. Do you have a gist of all your code somewhere?

I am putting this here from my own use as well as others... not entirely sure what the small differences are here: http://en.newinstance.it/2010/05/23/git-autocompletion-and-enhanced-bash-prompt/

autocompletion? This is relevant to my interests...
