Huh, that's pretty nasty indeed.

Not quite. In a hack I'm doing, I want to define a binary boundary in
the text (in the sense: above/below), and I do that by changing the
background color of one of the two.

I just overlay the region I'm interested in, but I want to extend the
background color of the face to the end of the frame, since it creates a
visually ambiguous situation otherwise (besides not looking good).

Maybe I can just temporarily extend the buffer content instead, but I
would loose the EOF fringe indicator and need to calculate how much
lines I need to append...
