With hi-lock-mode, either overlays are, or font-lock is used. I`d have
to check if it potentially uses both. Perhaps I can somehow make it use
overlays just to see what happens.
My understanding was that it may depend on the display/terminal whether
font-lock or overlays is/are used. This understanding seems to be
obviously wrong. They are suited for different circumstances.

What about it? Does it use overlays?
