What is the significance of this locale being "Gibberish"?
Currently, for any string, we give "### gettext poison ###" or
something but the only thing we care about in the poison mode is
that it is different from the message id, no? I was wondering if
these phony translations can be something simple like "Add QQ at the
beginning of the message id string" and still can catch mistakenly
marked messages that come from the plumbing layer, or something.
As you have already written a printf skipper that looks fairly
conservative, perhaps I shouldn't be worried too much about it, but
we seem to be spending considerable effort on the "poison", and it
makes me wonder (even though no better alternative comes to mind) if
we could do better. The reason we do "poison" (be it the current
one or locale based one) in the first place is so that we want to
make sure messages from the plumbing are not marked for i18n, and we
do so by running our test under the "poison" mode that produces
output different from the in-code text that are marked for i18n,
which somehow feels quite a roundabout way of doing so.

OK.

Thanks. I suspect two mode changes weren't intentional?
