[tor-commits] [stem/master] str_tools crop() issue with zero size



commit 2f31248f254d5dae2ed11c0a70b98e465c5b185c

    str_tools crop() issue with zero size
    
    Our str_tools crop() function provided a longer string than it should when
    given a width less than three. This is because ending with an ellipse subtracts
    three causing us to have a negative size, causing a wrap.
