From dc1e047baf7ab55f82eddc1c9a717eab556faefb Mon Sep 17 00:00:00 2001
From: Bruce Momjian <bruce@momjian.us>
Date: Sat, 7 Oct 2006 23:28:04 +0000
Subject: [PATCH] Allow HISTORY/history.html to be generated by removing <link>
 elements, per suggestion from Peter.  Without this, the main doc links
 prevent those files from being built.
