As I understand it, if a question is edited (from whomever for whatever reason) it will bump the question. [I don't know why that is considered to be a good idea in the first place but I don't want to go there.]
If a question is edited by others, it can happen, that it slightly changes the subject. Now if I (the op) hit the edit-button and revert some of the edits it will bump the question. But for no good reason: Nothing new has been added to the question; if anything, something old has been "added" to the question, but basically it would ask what it has been asking before the edits. So there is no justification for bumping it. But on the other hand, if the topic remains slightly changed it will draw "wrong" answers - that is answers, that are addressing the question with altered subject, and not addressing the op.
Now what I'd like to have is a checkbox that if checked prevents the system from bumping the question. Alternatively I could imagine a button that just rejects the edits that have been made that if hit, doesn't bumps the question but simply reverts it to it's previous state*.
Is there already such an option? If not this would be a feature-request.
*This would only be my second choice. As I am no native-speaker my questions tend to have some - erm... let's call them 'typos'. If those are fixed by others and I revert a question to it's previous state I'd undo the grammar-fixes too.
