The edit was rejected with this message:
This edit changes too much in the original post; the original meaning or intent of the post would be lost.
While I agree that the edit was pretty large, I disagree entirely that it changed the meaning or intent. The original form of the question is extremely rough; there's no way to improve it without massive change. But again, all the information I added came from the OP; I merely expressed his intent more clearly, I didn't alter it.
Once the edit was approved I was going to flag the question for re-opening, so please do that too. Actually I'm not sure whether edit rejections can be undone, so let me know if I need to propose it again.
