I don't think this a good idea since it will also cause Emacs to
refuse deleting the buffer without confirmation, and it will cause
autosaving to occur.
I think the current behavior is perfectly fine with regard to setting
the modification flag (or rather not setting it). The problem rather
is that C-x C-s consults nothing except the modification flag before
deciding not to save at all, and not asking a question about it. And
the prefix flag is already used for a different purpose, so we can't
use that to signal "I really mean it".
