Some might find it useful to put Amos' script in a bash function and
then put the current branch in the prompt. What I did was to put this
function in my .bashrc:

gitbranch () {
	. git-sh-setup-script &&
	branch=$(basename $(readlink $GIT_DIR/HEAD)) &&
	echo -n "" $branch ""
}

Then I modified my bash prompt:

export PS1='\[\033[1;31m\]\j$(gitbranch)[\w]\$ \[\033[0m\]'
                            ^^^^^^^^^^^

Now, if my current dir is not a git repo, I have my regular prompt. As
soon as I cd into a git repo, I get the current branch in the prompt, as
follows:

0[~]$ cd gitrepo
0 master [~/gitrepo]$ git checkout branch1
0 branch1 [~/gitrepo]$ cd ..
0[~]$
