I'd like to have this remark by animuson confirmed or refuted:
This is unverified, but I remember reading somewhere that an edit can only bump a question into the Reopen Votes queue once. Further edits would not continue bumping it into review. I could not find a source for that, though.
I could not find a source, either. There is an explanation of how edits send questions into Reopen queue, but it does not address this point.
My reason for asking: I often see questions with minor formatting edits (made by someone other than OP) in the Reopen queue. The reviewers decide to Leave Closed, since the reason for closure still applies. Suppose that OP edits the question later; will the edit send it to be reviewed again? If not, this means that minor edits to an on-hold question reduce the chance of the question being reopened.
