This is an incompatible change and there's no point in making it now.
However much better this seems now, that ship sailed 12 years ago in
Netscape 2 (beta). We do not get any bugs about this at
bugzilla.mozilla.org, and I've never heard of it as a recurrent cause
of real-world confusion and bugs, which might justify an incompatbile
change, if there is no content on the crawlable web that depends on
null => "null" and only content wishing null => "". So ES4 should
remain compatible with ES1-3 here.
