24.3; global-hl-line-mode + text-scale-adjust + next-line + scrolling |

With global-hl-line-mode enabled (but not local hl-line-mode,
which is implemented differently) and with a smaller font via
text-scale-adjust, scrolling off the bottom of the window with
next-line gets incredibly glitchy.
Recipe:
* emacs -Q
* Visit a file or add text with more lines than the current window
* M-x global-hl-line-mode
* C-x C--
* Hold down C-n

None of these are reproducible with the current trunk, so I guess my
latest changes fixed them all indirectly. I'm closing them.

I can't. So please file a new bug report ;-)

What do the following report in each one of the 2 above-mentioned
situations, i.e. before C-n would scroll, and before it would move?
M-: (pos-visible-in-window-p t nil t) RET
M-: (posn-at-point) RET
M-: (default-font-height) RET

No, it isn't, as that bug is already solved. I guess it was easier
than I thought at the time.
