Subject: [PATCH] (Bug 40860) make purgeRedundantText not fail on pre MW1.5
 records
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Archive records for deleted pages do not have an ar_text_id,
if they were deleted before big schema overhaul in MW 1.5.
This script was assuming all archive records had an ar_text_id.

Patch by Dévai Tamás.
