    Special-case right-dragging of a numbered cell off the grid.
    
    Chris Boyle reports that if you right-drag a numbered cell off the
    grid, _all_ numbered cells (except the immutable initial clues) get
    reset to blank, because this is treated as an attempt to erase a whole
    chain of linked cells (of the form a,a+1,...,a_k) and the cells with
    definite numbers are all treated as 'chain 0'.
    
    In that situation, I now substitute the same behaviour you'd get by
    left-dragging the numbered cell off the board, i.e. erase _just_ that
    cell and not the whole of the rest of the puzzle.
    
    (The previous unintended behaviour was a UI action you surely never
    want - and Chris also reports that due to the Android front end's way
    of representing right-drags, it's especially easy to hit by mistake.)
