Maybe we are not talking about the same thing.  I meant these
messages:

  http://lists.gnu.org/archive/html/emacs-devel/2014-10/msg00705.html
  http://lists.gnu.org/archive/html/emacs-devel/2014-10/msg01039.html
  http://lists.gnu.org/archive/html/emacs-devel/2014-10/msg01055.html

I don't see the special case of zero discussed back there, so perhaps
this is a different problem.
