So, to be clear, there was at one time debate over whether null -> integer
yields 0 should be in the standard, and in the end that was intentionally
omitted? So the error is in the editing--the stray "except as previously
specified" was accidentally left in referring to nothing?

Yes. And the general evolution of things has been away from segmented/exotic
addressing schemes to flat memory addressing. For good reasons, too ;-)
