    shell: update eggfindbar label only if the text changes
    
    This allows to avoid updating the GUI when the label to update
    has not really changed.  By doing this, it helps to reduce penalty
    performance when the caller makes multiples "updates" in a short
    period of time without really changing the label itself.
