(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))

Could you try the following patch? It is for Emacs 23.2 or the
emacs-23 branch.

Sorry, two occurrences of the following condition in the patch

I applied it to Emacs 23.2 and the problem is gone for me.
Thank you! Looking at the patch, fixing this required quite some work.
