How does one bring inappropriate or malicious editing to the attention of moderators? I know the question or answer itself can be flagged, but that's not what I'm asking about. I don't want to flag the content of the answer, especially since I will have fixed it anyway. I want to bring the malicious behavior to the attention of the moderators. There seems to be no "flag" button in a particular edit. I'd expect to find it right next to "roll back" if there was one.
There have been a few cases recently where a user has edited answers knowing full well he was changing author intent (the author explicitly told him this previously). The purpose was clearly to annoy the author, and the edits were even re-done after having been rolled back. In other cases, a typo or two were fixed, but then that used as a opportunity to change known author intent. Since this continues to happen, I looked for a way to flag the edit itself, but found no such mechanism.
How should I handle this if I encounter another such deliberately malicious edit?
