line-spacing and (recenter -1)

[SAITO Takuya]

(recenter -1) does not show point at the bottom of the window
if line-spacing is set to positive integer.

Start emacs -Q, and evaluate below:

(progn
  (setq line-spacing 1)
  (dotimes (i (window-height))
    (insert "\n" (int-to-string i)))
  (recenter -1))

Then, point is displayed at the center of the window.
But point should be displayed at the bottom of the window like Emacs-21.3.
