If you need a buffer position, then window-hscroll is not what you
want, because it returns the number of columns the window is
hscrolled. Also, when auto-hscroll-mode is 'current-line', the value
returned by window-hscroll is only correct for the current line,
i.e. the line which includes point.
If you need a buffer position of the first (leftmost) visible
character, then I think you want this instead:
(nth 1 (posn-at-x-y 0 (cdr (posn-x-y (posn-at-point)))))
