From 74a0d26d0ec77d9861daab5233e231de47f154f8 Mon Sep 17 00:00:00 2001
From: dominik <dominik@openttd.org>

Subject: [PATCH] (svn r1157) Enhanced the config file (openttd.cfg) to use
 another section type. "List sections" as opposed to "variable sections"
 contain a list of values, separated by a new line. This is now used for the
 [newgrf] group. You have to edit each line in this section from e.g. "0 =
 firstset.grf" to only "firstset.grf".
