Sorry for that, done.

I think current change can make sure nothing wrong.

Done

Because 'bitsetbit' and 'bitgetbit' do not have to calculate bit size by 'multiply 8',
so I think it seems need not to change it.

As above, it need not to touch 'bitgetbit' and 'bitsetbit'.

Thanks a lot for the detailed review again, and changed patch attached.
