    Doc: improve example for intarray's uniq() function.
    
    The previous entry invited confusion between what uniq() does
    by itself and what it does when combined with sort().  The latter
    usage is pretty useful so we should show it, but add an additional
    example to clarify the results of uniq() alone.
    
    Per suggestion from Martin Kalcher.  Back-patch to v13, where
    we switched to formatting that supports multiple examples.
