I just fixed the formatting in a question. Then, the OP turned the changes back (and added an apology for his formatting, so it probably wasn't intentional). Then, someone with not enough rep started editing as well.
The result is that I can't even rollback my old version, which had proper formatting. Is there any way to get around this? If not, can the editing system please be revised so that users with high rep can always edit, or at least always reject edits without requiring confirmation?
