Looking at the code, I'm still not sure what the meaning here is.

       (let ((sargs (and show-args
                         (delq nil (mapcar (lambda (x)
                                             (unless (macroexp-const-p x)
                                               x))
                                           (cdr form))))))

So...  if the elements in the rest of FORM evaluate to the same value,
they're included in the error output, but if not, not?  Uhm...
