In general I am happy that you are doing this work. However, I have just
realized that in some cases you are agreeing with my comments and then
you do not incorporate the changes which I was asking for. So, I would
be more happy if you instead of saying OK just do requested changes.
Otherwise you lose your and my time. Hence, I would like ask you to
check carefully all my comments for v4 and v5 (at least), apply all
requested changes with which you agree and then post v6.

Sorry for being blunt.
