From 132e0eda6c9f3f6a3e868e790b3cd355f55e9002 Mon Sep 17 00:00:00 2001
From: Karl Berry <karl@gnu.org>
Date: Thu, 3 Jul 1997 20:52:37 +0000
Subject: (\onepageout): Leave only one line space above the footline, to be
 more like plain.  Suggested by Stephen Gildea. (\evenfootline): Left one too
 many line spaces here, so reduce by two.

(\ifnottex): Another ignore command.
(\ifnothtml,\ifnotinfo): New commands.
(\doignore): Ignore brace characters, so mismatched braces in ignored
text do not cause complaints.
