Hmm... for `cl-defgeneric`, indeed, an empty body is normal (it doesn't
mean "return nil" but it means the absence of a default method).
Very good point.

I know Mattias played with this part of the code (mostly to try and
figure what to do about the ordering of the various possible kinds of
declarations, which is a related yet different issue).  Maybe he has
a more informed opinion.
