    Experimentally count copied cells on statusbar
    
    Added code to help evaluate the idea that displaying an iteration count
    on the statusbar is better than showing a busy cursor. If the entire
    operation is very fast, then flashing a busy cursor is just a nuisance.
    Showing a count on the statusbar serves the same purpose and is less
    obtrusive. However, if each iteration is very fast, then the overhead of
    displaying progress on the statusbar may be significant: in this case,
    it makes a half-second operation take approximately twice as long.
