This may be the dumbest question I've every asked, so go easy with me please! In SkinTemplate.php we have this:
$sitecss .= '@import "' . self::makeUrl( '-', "action=raw&gen=css$siteargs$skinquery" ) . '";' . "\n";
I understand that it helps when a useskin parameter is passed; what I don't understand is, why does it have to return a value when no such a parameter is passed? It can simply return "nothing", can't it?
