It has just been brought to my attention (well, rather: I found out) that on the German Wikipedia, if someone submits a text that constitutes a copyright violation, the sysops there immediately delete the complete page history and reinstate the most recent version before the copyvio.

This is a pretty serious issue; I'm pretty sure that this is not GFDL-legal (while, obviously, keeping the copyvio in the page history isn't either); it removes legitimate contributions from legitimate users; and less seriously, it messes up statistics.

I am therefore strongly suggesting that someone add a feature whereby a sysop can delete a single previous revision, rather than the entire history of a page.

It would probably suffice to delete just from the 'old' table; if you want to delete the most current revision, you should probably revert to an older version first anyway, thereby moving the one you want to delete to the 'old' table.
