Yup, you just said exactly the same thing as I already said in the
part you quoted. I still find the mixed use of off_t and size_t in
this patch iffy, and that was the secondary reason why the patch was
kept in the stalled state for so long. The primary reason was that
nobody tried to dust it off and reignite the topic so far---which I
am trying to correct, but as I said, this is just minimally adjusted
to today's codebase, without any attempt to improve relative to the
original patch.
I think we are in agreement in that this is not making things worse,
as we are already in the mixed arith territory before this patch.
