I asked a question which had an unrelated, but excellent answer.
I'd like to modify the question title to make it match the answer (and also to be able to ask the original question again more clearly, in hope someone will answer it), but this will make some comments obsolete, and I don't want to annoy the people who made them.
What is the best course of action in this case? Should I just accept the fact that some comments will be stale? Should I keep a small "edit" in the end to state "this has originally been asked as bla bla"?
