faster trim

[phpmyforum]

Maybe everyone had read this already... I think jQuery would really benefit from this:

Seconded. Specifically, I'd suggest the following version, which is Steve's trim12 function with the null-value fix from bug 1395:

trim: function( text ) {
	var text = (text || "").replace(/^\s\s*/, ''),
	    ws = /\s/,
	    i = text.length;
	while ( ws.test(text.charAt(--i)) ){}
	return text.slice(0, i + 1);
},

Diff against rev 2763.

No one interested?

I actually proposed one, and I think this trim12 is pretty much mine :)
