+Subject: tests: Explicitly unset LANGUAGE after setting LC_ALL
+
+As a GNU extension, LANGUAGE takes precedence over LC_ALL for
+gettext(3) whenever the locale is not C, causing tests that grep for
+specific English strings to fail when run in non-English locales.
+The upstream glibc proposal for C.UTF-8 would give C.UTF-8 the same
+special case as C here, but the implementation in Debian does not
+currently have this, so we have to unset LANGUAGE too.
