And if you are not scripting, then the completion script we ship (it was originally done for use with bash but I was told that it also can be used with zsh) may help.

Note that the completion script shows how to do this properly---if you are indeed scripting, it may be a good idea to study it, but the gist of it is:

	if b=$(git symbolic-ref HEAD 2>/dev/null)
        then
		echo "You are on branch ${b#refs/heads/}"
	else
		echo "You are not on any branch"
	fi
