Oh, thanks a lot, I've been searching the net for this for a long long
time today!

FYI, in shell scripting, here's the full solution to print the default
branch on the remote:

HEADREF=`git ls-remote
https://alioth.debian.org/anonscm/git/openstack/ceilometer.git | grep
HEAD | awk '{print $1}'`

git ls-remote
https://alioth.debian.org/anonscm/git/openstack/ceilometer.git | grep
${HEADREF} | grep refs/heads | awk '{print $2}' | sed 's#refs/heads/##'

Is there something quicker than 2 "git ls-remote" calls?

Christoph, do you think you could add this check in vcswatch? I don't
think I'm good enough in perl to do it in a non-too-hackish way.
