The ref "origin" will resolve to "refs/remotes/origin/HEAD", if it
exists. So you can use it as a shorthand for "origin/master" (or
whatever branch is most interesting to you on the remote).

It has been noted in the past that it should _not_ be automatically
updated, since it is really about "what is the user's preference for the
'most interesting' branch in this remote". And we don't want to
overwrite some preference that they specified.

So I think it makes sense to:

  - if it doesn't exist, set it up based on the remote's HEAD. Clone
    already does this, but "git remote add -f" should probably do it,
    too. I'm not sure if every fetch should do it.

  - give the user some nice interface (probably via "git remote") to
    move the pointer around (right now, it is "git symbolic-ref
    refs/remotes/$remote/HEAD refs/remotes/$remote/$branch").

  - give the user some nice interface to re-fetch the remote HEAD and
    update refs/remotes/$remote/HEAD with it. Probably as an option to
    the "git remote" invocation above.
