From 281cbfb883703dd38774831bd23f3a7df3d59ae5 Mon Sep 17 00:00:00 2001
From: Tim Starling <tstarling@users.mediawiki.org>
Date: Wed, 2 Sep 2009 01:59:36 +0000
Subject: [PATCH] * Fixed CR r48837. Although using ids[]=x in the query string
 is wrong and broken, ids[x]=1 works just fine and is a convenient interface.
 * Fixed CR r49408: removed JS dependency for multiple revision
 delete/undelete. Using <button type=submit> we can submit the parameter
 "action=revisiondelete". The custom action is then distributed to
 Special:Revisiondelete, which can understand this kind of entry point with
 only minor changes. * Also used <button type=submit> to avoid submitting the
 htmldiff button caption back to the server * Show the same buttons at the top
 and bottom of the history page, refactored duplicated code
