    app: locales without ISO-639-1 codes should not be ignored
    
    Some languages have no 2-letter ISO-639-1. This is the case in particular
    for 3 languages we have translations for: ast (Asturian), csb (Kashubian)
    and nds (Low German), which have only 3-letter ISO-639-2/3 codes.
    They were not visible in the list of languages in the Preferences dialog
    until now.
