line-spacing and garbage in fringe

[SAITO Takuya]

Start emacs -Q and evaluate below with C-xC-e:

(let ((lines 2)
      (spacing 1))
  (setq line-spacing spacing
        indicate-buffer-boundaries t)
  (insert (make-string (window-height) ?\n))
  (goto-char (point-min))
  (message (make-string (* (window-width) lines) ?.))
  (scroll-up 1))

then, garbage is displayed in right fringe.

Above code reproduces this bug with
(frame-parameter nil 'font)
=> "-Adobe-Courier-Medium-R-Normal--12-120-75-75-M-70-ISO8859-1"

If you use different font, you may need different value of
`lines' and/or `spacing'.
