Thanks for saving me from having to say it ;-)

I've reworded these while queuing.  See below.

Note that I toned "should be replaced" down to "should have been".

I'd consider this kind of change falls into the "Yes, it would have
been better if it were written like so from the beginning, but it is
dubious that it is worth the engineering time and effort to go back
and change it spending reviewers' bandwidth" category.  I'll still
take this patch as it is a contribution from a new contributor,
though (it's like reviewing and queuing microproject---the cost in
such cases is not attributed to code churning alone, but it also
benefits onboarding).

Thanks.
