github should do what repo.or.cz does:

	ln -s .../linus.git/refs digispeaker.git/refs/forkee

That way the refs available in Linus' tree are also available
in your tree as Git will transparently follow the symlink.

However you have to be careful to make sure `git pack-refs` isn't
run with `--all --prune` as it will delete the refs from linus.git
when executed in digispeaker.git.  Fun times when I did that to my
own repository one day.  ;-)

Though we probably should fix Git to be somewhat smarter.  But
until that stable binary is available, the symlink trick above
is a good work around.
