[Bug: xemacs-beta tip] decade-old version of texinfo.tex

[Samuel Bronson]

Hey, I just noticed that there's a copy of texinfo.tex in the man/
directory that identifies itself as:

\def\texinfoversion{1999-09-25.10}

whereas the latest
<http://cvs.savannah.gnu.org/viewvc/texinfo/doc/texinfo.tex?root=texinfo&view=markup>
is:

\def\texinfoversion{2010-09-06.17}

Considering that most TeX distributions probably have this file
anyway, I would just suggest removing the file from the repository,
and adding a note to man/README just in case there actually is a TeX
distro without texinfo.tex.

(I was going to suggest adding the latest, but then I noticed that it
was GPLv3...)
