I hope this doc page explains this well enough. I haven't searched for everything this would cover, but "recently" got me a ton. I tried to put the right dates in the articles where possible, so there are a few that got "fixed" but it wasn't often, and I didn't want to guess incorrectly.
I will add that now that this includes the 'fix' template it wouldn't hurt to create other meaningful inline cleanup templates. This one's first 'cause it's been bugging me forever. -- B.S. Lawrence 14:22, 19 March 2011 (EDT)
