Re: static declaration inside `window_scroll_pixel_based' in window.c

>From my earlier message:

   Anyway, if the above quote from `(elisp)Writing Emacs Primitives' does
   apply here, the problem would be easy to fix with the following patch,
   which I can install if desired.

No, I responded too quickly.  The patch is incorrect, since it always
re-initializes preserve_y to -1 at the start of `window_scroll_pixel_based',
defeating its static-ness. 

Sincerely,

Luc.
