I've looked into this, and decided not to follow common_list.  That's
because I've hacked the path.c code to treat refs/worktree specially;
it's under refs (common), but it's per-worktree, so it's special-cased.
You may have seen this in the per-worktree-refs-for-bisect thread:
http://permalink.gmane.org/gmane.comp.version-control.git/275673

This will require some special-casing in the alternate backends, but
they can use common the is_per_worktree_ref function.
