Looks good to me, thanks

    The encoded distance bits are zero, but the distance that is
    calculated from this is actually equal to 16384. So correct
    this statement to read that the 0001HLLL instruction means
    EOS when a distance of 16384 is seen. This matches with the
    description of the instruction itself later on.
