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);

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

I think I'll add  this trim function. We need to do some tests to verify it's a good choice for most situations.

After fixing #4037, .trim() is no longer used in jQuery core - FYI.
