Ted mentioned in the wart thread that having multiple branches per repo
means that the standard bash prompt isn't as much help as it could be.

For what it's worth i'll post a little script i've been using for quite
some time that helps a little.  It's called git-PS1 and is used by
including it in your bash PS1 variable like so:

export PS1='$(git-PS1 "[\u@\h \W]\$ ")'

If you're not in a git repo, the bash prompt you pass on the git-PS1
command line is used instead.  If you are in a git repo, you'll get
the following as a prompt:

[branch!repo/relative/path]$ 

Where "repo" is the basename of the path to the root of your repo.
An example would look like this:

[master!linus-2.6/Documentation/vm]$ 

Cheers,
Sean


#!/bin/bash
BR=$(git symbolic-ref HEAD 2>/dev/null) || { echo "$@" ; exit ; }
BR=${BR#refs/heads/}
REL=$(git rev-parse --show-prefix) 
REL="${REL//%\/}"
LOC="${PWD%/$REL}"
echo "[$BR!${LOC/*\/}${REL:+/$REL}]$ "
