texmathp.el is in AUCTeX, and we have in there

;; texmathp.el -- Code to check if point is inside LaTeX math environment
;; Copyright (c) 1998 Carsten Dominik
;; Copyright (C) 2004 Free Software Foundation, Inc.
;; texmathp.el,v 1.28 1998/11/23 15:19:44 dominik Exp

Ok, here is the crazy thing.

In 2003, Carsten Dominik assigned "all right and title" in texmathp.el
to the FSF (for program Emacs), after having previously assigned all
past and future changes to it (also for program Emacs).  But
texmathp.el is not even part of Emacs, whether released or in CVS.  As
far as I can see, it is only distributed with AUCTeX at the moment.
Does that mean that we can change the copyright notice in AUCTeX to be
FSF only without Carsten having to sign for AUCTeX specifically?

Should tex-mode.el be made to rely on texmathp.el if that improves
things?  AUCTeX is slated for inclusion into Emacs a few years from
now, anyway.
