[issue36564] Infinite loop with short maximum line lengths in EmailPolicy

As for the other, I don't see the need for a custom error.  It's a ValueError in my view.  I wouldn't object to it strongly, but note that this error is content dependent.  If there's nothing to encode, you can "get away with" a shorter maxlen.  Though why you would want to is beyond me, and that's another reason I don't think this warrants a custom error class.
