 should be NULL, not zero", I fixed that for r.los some months ago; maybe
 the code is related & the patch near the same? (no idea, but it would be
 worth a quick look to check)

 To what kind of output does this "NULL, not zero output" refer to? Binary,
 i.e. NULL = not visible, 1 = visible instead of zero = not visible, 1 =
 visible? Or viewing angle or elevation difference?
