It's unfortunately not so easy.  The problem you have to solve is D/F

branch and reflog for 'foo' branch.

I'm going to read up on Jonathan's pointers. But I do not really
see the problem above. If the reflog already exists, the new branch
simpliy continues using it. So if the branch is re-created, it's as
if the branch had never been deleted.

Or possibly we add a special reflog entry which points the branch
to a zero sha to signify that the branch had been deleted.
