js> f = function( ){ return (aaaaaaaaaaaaaa && bbbbbbbbbbbbbbbbb && ccccccccccccc && ddddddddddddd) && eeeeeeeeeee && fffffffffffff && gggggggggggggg; }

function () {
    return aaaaaaaaaaaaaa &&
        bbbbbbbbbbbbbbbbb && ccccccccccccc && ddddddddddddd &&
        eeeeeeeeeee && fffffffffffff && gggggggggggggg;
}

js> eval(uneval(f))

function () {
    return aaaaaaaaaaaaaa &&
        bbbbbbbbbbbbbbbbb &&
        ccccccccccccc &&
        ddddddddddddd && eeeeeeeeeee && fffffffffffff && gggggggggggggg;
}

Both decompilations have bogus wrapping.  jsfunfuzz noticed because they differ.
js> f = (function( ){ return (aaaaaaaaaaaaaa && bbbbbbbbbbbbbbbbb && ccccccccccccc && ddddddddddddd) && eeeeeeeeeee && fffffffffffff && gggggggggggggg; }

(function () {return aaaaaaaaaaaaaa && bbbbbbbbbbbbbbbbb && ccccccccccccc && ddddddddddddd && eeeeeeeeeee && fffffffffffff && gggggggggggggg;})

js> eval(uneval(f))
(function () {return aaaaaaaaaaaaaa && bbbbbbbbbbbbbbbbb && ccccccccccccc && ddddddddddddd && eeeeeeeeeee && fffffffffffff && gggggggggggggg;})
