Browsing around the wiki, I found "WikiPedia" interwiki goes to http://en.wikipedia.org/wiki/blah_blah, however Wikipedia always redirects your link to HTTPS unless you're in China or such (see ). Therefore there is no merit if you link it to http: you will be redirected to https anyway.
IIRC MoinMoin's interwiki map is something of a file and that needs to be edited; Since this is not a high priority (you don't get dead link) please remember to modify this when you modify interwiki map next time.
PS. I am not subscribed, CC me on any reply.
