cg-clone already does this. One tricky thing with the selective
cloning is that you want to pull the named head plus all its related
objects, and then pull only the _relevant_ tags. There's been
discussion of pulling tagsrefs+related tag objects and then pruning
any tagrefs+tagobjects where the commit is unreachable with the
objects you already have. You surely remember my 'git-rev-parse  is
crashing' thread.

If you just pull tagrefs and all the objects needed for them, chances
are you'll get the whole repo anyway ;-)
