Four unclear Mwe messages

i asked Michael Dale on IRC to document them. He said yes! (so it should be done shortly)

Thank you.

I saw that you changed the links to the messages to the {{msg-mw}} template. It makes them link to Dutch translations, for example MediaWiki:Mwe-imported from/nl. Is it intentional?

That should be updated on display. Caching issue, maybe?

Now it's en. I didn't do anything special to refresh the page. Strange.
