I thought at first you could use "grep" here, since we know that the
name of the file would appear untranslated. But I think the way
GETTEXT_POISON works, it actually eats the whole string, including
placeholders (which IMHO is a failing of GETTEXT_POISON, since no real
translation would do that, but not worth caring too much about).

When Ævar's dynamic gettext poison topic was discussed, there was an
idea or two floated for a possible follow-up to introduce a true
"fake translation", replacing e with é, n with ñ, etc., while
keeping the printf formaters intact.  When that comes, we should be
able to use grep and that would make the result more robust than the
current test_i18ngrep that always pretends to have seen a match, but
that hasn't happened yet.
