    Clarify klist -s documentation
    
    The documentation for klist -s erroneously suggests that it doesn't
    affect the exit status behavior and that it merely checks for the
    existence of the ccache (only mentioning the expired ticket check at
    the end).  Make it clearer and simpler, but avoid going into a lot of
    detail about the nature of the expiration check.
