RegExp.$1 spec

[Brendan Eich]

Ugh, I'd forgotten about this. If it's implemented in all of IE,  
Mozilla, Opera, and Safari, then it might be best to codify it in  
ES4. OTOH we would then want to deprecate it. If we can let it alone  
as a de-facto standard, not make it normative in the de-jure spec,  
and thereby more effectively deprecate it, that would be best IMHO.
