P.S.: There is one thing I do not understand though.
language of simple.wp is "en", but MessagesSimple.php seems to be taken
into account (instead of "edit" it has "change" in the UI, one of
changes in MessagesSimple to MessagesEn). So it seems that the language is
"simple" -- why does it say "en" in the siteinfo?
Are you sure this isn't just because someone edited
[[MediaWiki:whatever]] on simplewiki?
