git-PS1 bash prompt setting

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]$
