I'm leaving for a short holiday tomorrow, but will do when I come back.

What happens on savannah is that the sysadmins set up an empty GIT
repo with access, and leave it to you to push the stuff.  Of course,
if the initial import gets packed automatically, that's also ok.

Perhaps ; from a UI viewpoint, it would be nice though, even if it
were aliased to a simple push. (Darcs has a get command analogous to
git-clone, but also a put command to which git lacks the equivalent).

No, I don't understand. In the fetch all the objects with their SHA1s
were already downloaded. I'd expect that the fetch with a refspec
would simply write a HEAD and a refs/heads/master, and notice that all
the actual data was already downloaded, and doesn't download it again.
