[math-fun] Latto's proof of critical point theorem

Andy Latto:

Aha. Right, this is now trivial.

I'm a little confused. My statement is false, *and* you have a counterexample, *and* it's trivial?

--sorry, to be more clear: I think you had it right, and not only that, have reduced it to a triviality, while my old proof is now seen to have been highly overcomplicated.
