I guess current-line is wrong the documentation for windows start
gives `window-start' is a built-in function
(window-start BUFFER &optional WHICH-FRAMES WHICH-DEVICES) and the -1
is probably wrong too.
Documentation:
ans search all devices.
I can't see how if fits. Try this
(defun current-line ()
"Return the vertical position of point within the current buffer."
(+ (count-lines (point-min) (point))
(if (= (current-column) 0) 1 0)))
