The signature is wrong from the start. Directly call them without
providing these optional (mandatory-in-disguise) arguments throws an
error, unlike commands defined by defun-rcirc-command which correctly
handle &optional arguments. I'll commit the patch as is if no
objections. Thanks for raising the issue.
