----------------
- Look for ``.po`` files in any ``LC_MESSAGES`` directory. It no
longer matters if this is contained in a language directory within a
``locales`` or ``locale`` directory, as they could also have names
like ``plonelocales`` or ``locales_for_version_2_only``. Note that
in Plone ``.po`` files can also be in an i18n directory, but those
should not be compiled; this does not have a ``LC_MESSAGES``
directory, so we automatically skip it.
