From cc4d91d75131c5e4f5f644d3a53f3687925958f5 Mon Sep 17 00:00:00 2001
From: Karl Berry <karl@gnu.org>
Date: Wed, 18 Jun 1997 19:58:18 +0000
Subject: (\oddfootingxxx), (\onepageout): Leave space for the footline if
 present. (\everyfootingxxx, \everyheadingxxx): Call \oddfootingxxx and
 \evenfootingxxx instead of repeating their code. From: Stephen Gildea
 <gildea@intouchsys.com>.

(\setfilename): Read texinfo.cnf if present.

(\indexdummies, \indexnofonts): No-op additional commands @result @equiv
@expansion @print @error @point.
From: Dave Bodenstab <imdave@ais.net> (for texi2www doc).
