        - Fixed <rdar://problem/4534904> please do not treat "debugger" as
        a reserved word while parsing JavaScript (and other ECMA reserved
        words)

        We treat "char" as a reserved word in JavaScript and firefox/IE do
        not

        (1) I unreserved most of the spec's "future reserved words" because
        they're not reserved in IE or FF. (Most, but not all, because IE
        somewhat randomly *does* reserve a few of them.)
        (2) I made 'debugger' a legitimate statement that acts like an empty
        statement because FF and IE support it.
