Streams: Consistent behaviour when reading from stream with error.

Browse source 
The streaming operator doesn't short-circuit, consider the following
snippet:

    void foo(InputStream& stream) {
        int a, b;
        stream >> a >> b;
    }

If the first read fails, the second is called regardless. It should be
well defined what happens in this case: nothing.
