somebody unhappy.

While designing please consider supporting at least 3 options:
- extend highlighting to the window edge as most faces do now;
- highlight only to the end of lines as underline does now;
- limit highlighting to a fixed customizable column like
 display-fill-column-indicator defaulting to fill-column.

Hi Juri:

Up to now we are only dealing with the first two cases... The third one
will add even more complexity (and corner cases when dealing with dfci)
for a very low gain (in my opinion) because I don't find yet any use
case for it. I am not telling it is impossible, just unneeded.

If you have a good use case for it, please share it.
