    hanging punctuation?'' asked Alice, with a puzzled frown.  `Well,
    y'know, \mbox{actually},' answered Bill, `I'd rather demonstrate
    it than explain it.' ``Oh, now I see.  Commas, periods, and quotes
    are allowed to stick out into the margins, if they occur next to a
    line break.'' `Yeah, I guess.' ``Really! But why do all your
    remarks have single quotes, while mine are double?'' `I haven't
    the foggiest; it's weird. Ask the author of this crazy book.'
