    Mines: show the number of safe squares left, if it's small.
    
    This is intended to make life easier for the _really_ dense grids in
    which the generator algorithm falls back to a bare clearing, a tightly
    packed section round the edges, and a fringe of deductions required in
    between.
    
    In that situation, you can deduce _in principle_ from the remaining-
    mines counter that there are (say) one, or two, squares left to be
    uncovered before everything remaining has to be a mine. And often the
    game will require that deduction in order to solve it all by pure
    logic. But actually doing it requires counting up the huge number of
    covered squares in an irregularly shaped area and subtracting the mine
    count in the status line, which is a real pain.
    
    In fact, people failing to do that are the biggest source of (wrong)
    bug reports about Mines games having no solution, so with any luck
    this will make my own life easier.
