   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

Well, there you go -- more elegant by one funcall.  Congrats!

(I think i wrote it that way to make it clear to me since i
see/type/think ‘(null (cdr ...))’ more or less idiomatically.
If i use ‘when’, i would have to add a comment to myself.
Normally, i'm not against comments, but this time, meh... :-D)
