I now beefed up the old highlighting routine a bit, such that hovering to interpose a Pawn in the move diagrams now also works for leaps of 4 and 5. (That routine was written before it was possible to even define such leaps with the aid of X and Y.) So nWX, nDX, nAY, nGY now should all work. Larger leaps will still fail; nHX would test only the even intervening squares.
