I just sent v5.
If for whatever reason, you or anybody else think that the comment is
not good, would you mind proposing a comment that would make everybody
happy so that the patch goes thru?
And if you or anybody else does not want the patch, could you please say
so as well?

I have to admit this process (sending patches and getting it reviewed)
could benefit from more clarifications.
For example, the process could say that at least 2 reviewers must agree
on it (on the comments made to the patch and on the patch itself).
I could also say that reviewers are to express not only their opinion
but to clearly and unequivocally accept or reject.

For instance, right now, it is not clear to me if your comments are
"nice to have" or "blocking" the patch.
I don't know if the patch is welcome or not, etc.
So I submitted v5, but maybe it was not even necessary, it's hard to
know where in the submission process we are.

By the way, I know some people like the command line, email, etc. but
there ought to be other tools better suited for patch review...
