Hyperbole (KOTL) set-fill-prefix misuse?

In xemacs-packages/hyperbole/kotl/kotl-mode.el is this function: (defun kotl-mode:set-fill-prefix (turn-off) "Sets fill prefix to line up to point. With prefix arg TURN-OFF or at begin of line, turns fill prefix off." (interactive "P") (set-fill-prefix (or turn-off (kotl-mode:bolp)))) But set-fill-prefix does not take any arguments, on either Emacs or XEmacs. I suspect that this was intended: (defun kotl-mode:set-fill-prefix (turn-off) "Sets fill prefix to line up to point. With prefix arg TURN-OFF or at begin of line, turns fill prefix off." (interactive "P") (save-excursion (if turn-off (beginning-of-line)) (set-fill-prefix))) Opinions? -- Jerry James http://www.ittc.ku.edu/~james/
