matchByName breaks under jQuery 1.5.1 on ie8

[si-g]

matchbyname causes a syntax error when using jquery 1.5.1 on ie8
e.g.

selector = "[name=ctl00$ctl00$_mainContent$_mainToolbar$_flightSearch$_origin], [id=ctl00$ctl00$_mainContent$_mainToolbar$_flightSearch$_origin]" fails

Seems to require the single quotes e,g,

function matchByName(name) {
var selector = "[name='" + name + "'], [id='" + name +"']";
// include elements in this set that match as well a child matches
return self.filter(selector).add(self.find(selector));
}
