I've run into a small problem just today. I was reviewing a question and tried to re-format the question since the OP seemed to have missed some lines that clearly were part of the code (s)he was trying to post.
However, once I was finished, I received a message telling me my edits were rejected because they required more than 4 non-blank edits to pass.
The first time it happened I cancelled my edits. The second time I corrected some minor grammatical mistakes.
Is this a new feature? How else should I have proceeded?
