Yeah, the diff turned out less noisy than I'd feared. So here's a v2. It
does the refactoring we've been discussing, which is now in patch 2
(since the extra function is no longer needed). And then it was actually
pretty easy to fix the other weird "your unborn master does not match
the remote's master" problem on top. I _think_ that's the right thing to
be doing, but see the discussion in patch 3.

I'll skip the range diff, which is mostly unreadable (the only readable
part is that I did s/empty/unborn/ in the tests, as discussed).

  [1/3]: clone: drop extra newline from warning message
  [2/3]: clone: propagate empty remote HEAD even with other branches
  [3/3]: clone: use remote branch if it matches default HEAD
