Quick View: handle subsequent images in url()

[redmunds]

This is for #3581. Code was only looking for first url() match.

Head's up: @gruehle, @RaymondLim.

nit: you can replace while loop with do ... while and remove this line.

Thanks for the suggestion, but I don't think it improves the code:

    do {
        urlMatch = urlRegEx.exec(line);
        if (urlMatch && pos.ch >= urlMatch.index && pos.ch <= urlMatch.index + urlMatch[0].length) {
            tokenString = urlMatch[1];
            break;
        }
    } while (urlMatch);

There's 1 less line that calls urlRegEx.exec(line), but there's an extra check for urlMatch, so it checks urlMatch twice on every loop.

I'm going to leave it like it is.

Done reviewing. Just one minor nit.
