I just ran across a proposed edit to an answer that was already accepted. The edit was not something to fix grammar or spelling, but rather to add another option into the answer different from what the answered had already suggested. The edit was also done by an anonymous user with 1 rep.
My inclination would be to post the (short) edit as a comment and explain the situation briefly, then reject the edit. That way the answerer can judge whether or not to include the edit.
What are the thoughts on this?
