Why are you asking the title from Article when you just used $title to create Article object?
No special reason.. it doesn't make any difference I suppose
This wasn't merged yet (I see no follow-ups). If that is the case, do we still need it? 1.19 was branched after this so it'll be in 1.19.0 and already is in 1.19wmf1. Untagging for now, feel free to re-tag.
Now that it's in 1.19wmf1 (and actually deployed on most wikis), it doesn't need to be in 1.18wmf1 anymore, so it's okay.
