FYI: update texinfo.tex

[Alexandre Duret-Lutz]

Texinfo is maintained at
  https://developer.berlios.de/cvs/?group_id=1217
until Savannah resurrects.  This new version come from there.

(However this is not the last version of texinfo.tex committed.
Later versions, at least up to 2003-12-08.17, fails to compile
automake.texi...)

2003-12-10  Alexandre Duret-Lutz  <address@hidden>
