Right.  So we hack our own test library, and we use it to determine that
emacs 23 will break our code.  We then put up a notice telling the end
users that they shouldn't uprade their version of emacs. They do it
anyway, and begin complaining, but everything's cool, because we can
point at the notice we put up.

Note that in this case, you'd have to have pretty good test coverage
to have a hope of noticing this problem, because it's not the kind of
breakage that anyone would've anticipated as being at all likely.
