Bug in the function matcherFromTokens

[[email protected]…]

When a query on before fails it don't load the page correctly, I try to fix it like this.

function matcherFromTokens( tokens ) {
	var Tokens_type="undefined", leadingRelative=false;
	if(typeof(tokens[0])!="undefined"&&typeof(tokens[0].type)!="undefined"){
		Tokens_type=tokens[0].type;
		leadingRelative = Expr.relative[ Tokens_type ];
	}
	var checkContext, matcher, j,
		len = tokens.length,
		implicitRelative = leadingRelative || Expr.relative[" "],
		i = leadingRelative ? 1 : 0,

		// The foundational matcher ensures that elements are reachable from top-level context(s)

I just check the existence of the params. I think it is not a real bug, but this code fix a problem.
