    Galaxies: disallow placing an edge touching a dot.
    
    Trivially, no edge of this kind can be part of any legal solution, so
    it's a minor UI affordance that doesn't spoil any of the puzzly
    thinking to prevent the user accidentally placing them in the first
    place.
    
    Suggestion from Larry Hastings, although this is not his patch.
