I've recently asked a question for which I have two good answers. I've up-voted both answers, but not yet designated one as the "correct" answer.
Since the answers have been posted, I've realized I made a mistake in my question: I incorrectly asserted that two similar commands gave the same output, when in fact they do not. I don't know how I managed to screw that up, but I did.
I've read an answer with advice on a similar situation, but it's a bit different situation.
My question is what to do about my screwed-up question?
