On the contrary, that's so cool! I had to think and think and
think before I realized it is 0 or 1 file -> don't do it, but
2 or more files -> do it.

Only ... isn't `unless' and `null' = `when'?

(unless (null (cdr '()))    1) ; nil
(unless (null (cdr '(1)))   1) ; nil
(unless (null (cdr '(1 2))) 1) ; 1

(when         (cdr '())     1) ; nil
(when         (cdr '(1))    1) ; nil
(when         (cdr '(1 2))  1) ; 1
