current-prefix-arg is used. If cmd1 changes it, anything can happen.
e.g.
(global-set-key (kbd "<f6>") (lambda () (interactive) (yffoo)))
(defun yffoo () (setq current-prefix-arg '(5)) (call-interactively 'yfbar))
(defun yfbar (&optional arg) (interactive "P") (message "arg is %S" arg))
hitting f6 will show that arg is (5) (which doesn't make sense in an
true interactive call)
