    completion: make typed-text cell more space forgiving
    
    We are often racing to do measurements and size allocations against round
    trips from the display server. Making this column able to contain an
    ellipsis allows the machinery to be more forgiving in case we get too small
    of an allocation inbetween roundtrips.
