This is one of these times when I find myself very fortunate for
being surrounded by competent contributors with good tastes, which I
may not deserve ;-)

Thanks for being thorough.

Having said that, it is only just a single comment, and it is too
much hassle to even think about what to do in the meantime while we
wait until such a change happens and an updated version of gettext
reaches everybody.  Let's take 2/3 as-is.
