Hi there,
Emacs just made my day.
(defun print-prefix-arg (arg)
"Print the raw prefix argument and its numeric value in the echo area."
(interactive "P")
(message "Raw: %s, numeric: %s." arg (prefix-numeric-value arg)))
C-u - 0 M-x print-prefix-arg
Raw: -, numeric: -1.
:-)
(It is not irrational - see simple.el, function `digit-argument' and the
comment therein. But it's still funny.)
Best,
--
