6553 have to draw a vertical border.
6555 * window.c (window_scroll_pixel_based): When scrolling down by
6556 screen-fulls, make sure it.current_y doesn't get negative because
6557 this would confuse move_iterator_vertically.

6560 the case continuation lines are involved.
6561 (try_window_id): Don't set the cursor into scroll margins.

6591 overlap with previous or following characters.
6592 (draw_glyphs): If background is cleared for hl == DRAW_CURSOR,

6953 * xfns.c (x-list-fonts): Copied from x-list-fonts.c; #include

10753 be in same section as initialized data. Reduces size of static
10754 heap section to that used during preload.
