From 80e2c3c940aeb3a0e97420c2e81fb137c7a370f0 Mon Sep 17 00:00:00 2001
From: Jacob Nevins <jacobn@chiark.greenend.org.uk>
Date: Mon, 7 Mar 2005 20:00:18 +0000
Subject: In contents lists, put <ul> inside <li> to make validator.w3.org
 happier (for all HTML flavours). Also add newlines to the contents output so
 that the source is vaguely legible. Couple of extra comments in the code.

[originally from svn r5453]
