Hmm. It sort of works:

  $ mkdir parent && (cd parent && git init)
  Initialized empty Git repository in /home/peff/parent/.git/

  $ git clone parent child
  Initialized empty Git repository in /home/peff/child/.git/
  warning: You appear to have cloned an empty repository.

So far so good...

  $ (cd parent && echo content >file && git add file && git commit -m one)
  [normal commit output]
  $ (cd child && git fetch)
  [normal fetch output]

But:

  $ (cd child && git pull)
  You asked me to pull without telling me which branch you
  want to merge with, and 'branch.master.merge' in
  ...

So it's not quite seamless. The problem is that we're not setting up the branch.master.* config on the empty clone. Nor do we set up refs/remotes/origin/HEAD.

On top of that, I get funniness between versions:

  $ ssh peff.net 'git version && mkdir foo && cd foo && git init'
  git version 1.5.6.5
  Initialized empty Git repository in /mnt/data/home/peff/foo/.git/

  $ git clone peff.net:foo
  Initialized empty Git repository in /home/peff/foo/.git/
  warning: You appear to have cloned an empty repository.
  $ fatal: The remote end hung up unexpectedly
