All engines are going to implement this anyway, so why make it Annex B only? I
wouldn’t restrict it to non-strict mode either, as this decision seems to be
purely based on the Firefox/SpiderMonkey bug that was discussed earlier.

In section 11.8.3 (Numeric Literals), the definition for
`DecimalIntegerLiteral` should somehow be tweaked to match that of
`DecimalDigits`, with the exception that if the first digit is `0` and all
other digits are octal digits (0-7) it must be treated as a legacy octal
literal.

Firefox is the only browser that throws on `(function() { 'use strict'; return
08; }())` and the only reason it does that is because of a bug (see my earlier
email). In general, strict mode does not matter here.
