From 7d27a815b614d93698b6d3de4c8a102e35d9fe99 Mon Sep 17 00:00:00 2001
From: Egbert Eich <eich@suse.de>
Date: Fri, 5 Mar 2004 13:40:24 +0000
Subject:   23.  Merged with XFree86 4.4.0. Added changes that went into
 infected        files. Reverted darwin/bundle/**/Credits.rtf to XFree86
 versions        to avoid future conflicts on ASCII but not humal readable
 files.        (There should probably be separate CreditsXorg.rtf files)      
  (Egbert Eich).
