Agreed.  When I do it by hand (but I shouldn't have to
do this by hand, git-clone-script should do it this way
if that's the best and most efficient) I usually link the
object directory then copy the rest of the stuff non-linked.

I keep hoping git-clone-script is going to be a good way
to clone two local trees.  Is my hope misguided?  :-)
