in directory, fix the listing of subdirs that reside in a subdirs that have spaces - #1253

decodeURI can throw... decodeURI('%f')

@hueniverse, so here I'm a bit confused.
Is it possible to request a not encoded url? yes (at least with the basic http module as server & curl it is possible)
is it allowed? isn't it a bad request? for example, is GET /dir/%/ allowed as a good request? shouldn't it be GET /dir/%25/ ?
It's also harder to test this scenario, since the hapi router.match doesn't match it (at least from what I see, I will dig a bit deeper).

@hueniverse, so I found out that route is actually decoding url component using these functions:

internals.setParam = function (name, value, params, paramsArray, isEmptyOk) {

    var isValid = (isEmptyOk || value);

    if (isValid &&
        params) {

        var decoded = internals.decodeURIComponent(value || '');
        if (decoded === null) {
            isValid = false;
        }
        else {
            params[name] = decoded;
            paramsArray.push(decoded);
        }
    }

    return isValid;
};


internals.decodeURIComponent = function (value) {

    try {
        return decodeURIComponent(value);
    }
    catch (err) {
        return null;
    }
};  

which ultimately means- a path that is not decoded correctly is invalid. However, note that it will return 404, and it will try to decode it foreach route.
