I just ran into a proposed edit to this question in the review queue. The edit seemed reasonable on the surface - there was some dead text from an image link that had been partially removed on a previous edit.
But when I dug into it, I was really uncertain about the whole thing. The question 'evolved' with a insertions, changes & deletions as it was being worked out. I suspect some of the alteration probably shouldn't have been made, but given the question as it is now, how should it be dealt with? There doesn't seem to be a good single point to roll it back to, but leaving it as it is seems to leave it in a state that's less useful to other who might have run into the same problem.
