More complexity than it is worth. We're already debating their utility. The
marginal utility of a plugin is even less :-)

Hmm. I think we'd have the plain text hash, and a second hash for the diff
data. Of course, old revisions don't store the plain text, but when we
restore it, we'll already have its hash (i.e. we computed it when the
revision first arrived; no big reason to toss it).
