I think the condition handler of `condition-case` should be of the form
(CONDITIONS . BODY) so I think having nil counts as a syntax error, tho
it's arguable since nil ≃ (nil . nil)

I wouldn't bother signaling an error when we interpret the code, but it
would be good for the byte-compiler to warn about it.
