(Note: This bug is also visible on Emacs 23).

Recipe:

* emacs -Q

* In the scratch buffer evaluate

  (progn
    (setq indicate-buffer-boundaries 'left)
    (insert (make-string 100 10))
    (goto-char (point-min))
    (forward-line 5)
    (redisplay)
    (set-window-vscroll nil 1))

* There are now two arrows in the fringe on the lower left side, but it
  should only be one at the bottom.

* Adding more 'set-window-vscrolls' will add more arrows. For example,
  this will create four:

  (progn
    (setq indicate-buffer-boundaries 'left)
    (insert (make-string 100 10))
    (goto-char (point-min))
    (forward-line 5)
    (redisplay)
    (set-window-vscroll nil 1)
    (redisplay)
    (set-window-vscroll nil 2)
    (redisplay)
    (set-window-vscroll nil 3))

* The same happens with pixel (fractional) scrolling, it'll just makes
  the arrows overlap:

  (progn
    (setq indicate-buffer-boundaries 'left)
    (insert (make-string 100 10))
    (goto-char (point-min))
    (forward-line 5)
    (redisplay)
    (set-window-vscroll nil 3 t))

Regards,
David

Actually, pixel-unit mouse wheel scrolling in the Mac port uses window
vscroll extensively, and this bug has been annoying also for me.

Thanks for testing.  I've installed it to the emacs-23 branch.
