Ok, I have been feeling uneasy about rename and reflogs for a while now.
 About removing reflogs too for that matter.

In my mind the ref log is about tracking what a ref points to.  So I
want to be able to say "what was next, yesterday".  Do I care if its not
there now?  Perhaps I want a rename to just put a rename from in the top
of the new reflog and leave the old there.

Yep, no idea how we would clean them up with this model.  But ...
