This miscounts from the very beginning.  I am not sure where the
mistake came from originally.

This too miscounts from the very beginning of this content; it is
likely that it was copied and pasted from the line above, which does
have a correct bytecount.

These are likely copy-and-paste from the above ;-)

I counted these myself before applying, and they look correct ;-)

Thanks.
