Small detour into MAINE.EXE because it has all the juicy algorithms that will
explain the remaining unknown members of the highscore data structure, and
there's this one code segment here we need to get out of the way first.
The same function appears unused in TH02's MAINE.EXE. Separate commit because
this was painful enough and we can link the C version into FUUIN.EXE right
now.
