If you can suggest a way to get horizontal bars that are ignored by
point movement without using newlines in overlays, then great. I
almost got there using :overline and :underline, but as far as I can
tell, there's no way to extend the line to the edge of the screen
without using an overlay with a newline.

If you just want to say that the region should be shown by
highlighting instead of horizontal bars, then *shrug*.
