That is correct. We are not asking for the GPL. We are asking for
the GNU Emacs (v19, I think) documentation license, which was,
unfortunately for the current situation, anonymous and unversioned.
I think of this license as approximately a special case of the GFDL.
Because both require that any redistribution take place under terms
_identical_ to the original, they are, however, mutually incompatible.
Whatever the FSF might decide to do with its policy on documentation
licenses, it shouldn't revert to a license that can only be specified
by quoting the whole thing; it would be asking for this situation all
over again. So no matter how you slice it, XEmacs would require an
specific sublicense from the FSF to incorporate portions of GNU Emacs
documents in the XEmacs documentation.

As far as I know, it didn't occur to us to change the license. There
was no discussion that I can recall until perhaps two years later,
which came to the obvious conclusion that changing the license was
impractical, and the discussion was immediately dropped.
