First, thanks for working on this! I'd love to make it straightfoward
to test a github branch with a single autopkgtest invocation.

I would actually like to generalize this, and use one and the same
method and syntax for both cases. Right now an url#mybranch argument
just does "git clone --branch mybranch url" which does not work for
these "floating" refs of PRs. But this seems to work:

  git clone url
  git fetch -fu origin $BRANCHNAME:testbranch
  git checkout testbranch

So the existing http://foo.org/proj.git#stable syntax (proper branch)
would continue to work, but you can then use
(which is what I use for systemd PRs).

Would that also work for gitlab?
