I agree it feels a bit out of place, and still think that
$ git branch --list HEAD
would be a good candidate to be taught how to print the current branch.
I suggested this in the previous iteration but either got lost in the
noise or was uninteresting. If the latter, I would love to receive
feedback on it.

Something like the following (not meant as a real patch), would show the
current branch when attached, (HEAD detached at hash) when detached, and
nothing if unborn branch.
This will also keep the current formatting git branch uses (which is
sliglty harder to parse). I view it as a plus. Otherwise people will
eventually start parsing it instead of using the recommended plumbing.
