This will cause havoc trying to keep straight 'official patches' from net
supplied patches. Net patches can be supplied relative to some well known,
official patch, but then all net patches after that will fail on the CRC.
Won't be too bad if the number of CRC checking patches are kept to a
minimum; otherwise there will be a lot of hand editing. Of course, since
this is being proposed as a solution to massive re-writes including gobs
of copyright code in the cdiff, all future patches would be difficult to
apply anyway, so this would be the obvious case that CRC checking patches
would be limited to.
