    uncompress: Avoid reading an extra byte

    When reading the next code in a stream, avoid reading an extra byte if
    we're going to throw it away. When there's no more bits to extract from
    the stream, bits will be 0 and we'll mask the read byte with 0 anyway.
    At worst, this will avoid reading one past the end of gbuf array (which
    is not possible in well formed streams).
