Query string isn't escaped

[ozten]

If you send a properly escaped url into url::Url and pass that into http_client, then the actual request will not be escaped.

Example:

let search_url = "http://localhost:8002/search/code?q=" +
        query.replace(" ", "%20");
let u: Url = url::from_str(search_url).get();
uv_http_request(u, options);

the debug output will be

Actual

rust: ~"http_client: writing request header: ~\"GET /search/code?q=navigator.id.get OR navigator.id.request HTTP/1.0

Expected

rust: ~"http_client: writing request header: ~\"GET /search/code?q=navigator.id.get%20OR%20navigator.id.request HTTP/1.0

I'm not sure if this fix is in Url or http-client.

Url looks like

{scheme: ~"http", user: None, host: ~"localhost", port: Some(~"8002"), path: ~"/search/code", query: ~[(~"q", ~"navigator.id.get OR navigator.id.request")], fragment: None}

I'm thinking http-client should escape query string before sending it.
