Sorry, I don't think I follow.  Does po4a understand Texinfo in
general and the @documentlanguage directive in particular?  If it
does, why doesn't it also know that en_US is the default when no such
directive is present?  And if it doesn't understand Texinfo, why would
the presence of @documentlanguage change anything in its output?  And
where would someone need to add the language string manually -- in
what file?

Thanks.
