I seem this would make its constructor more clearly.

I know it. First, I had thought replacing this `0` to `nullptr`. https://trac.webkit.org/browser/webkit/trunk/Source/WebCore/fileapi/FileReaderSync.cpp#L48 But I think it maybe better to use WTF::Optional. To make it more simply, Is replacing nullptr best?
