I'm afraid you still don't understand. This commit wasn't supposed to
have anything to do with bug #1220 (the commit description is
inconsistent and wrong too); the only valid patch for that was applied
correctly in September, as you noted.

The extraneous line in this commit wasn't part of any patch I've seen
(or I would have objected), it came out of blue air.
