My understanding is that anything which goes to a URL - a "one-bracket link" - gets treated as an external link and is nofollowed, regardless of where it goes; anything created as a wikimarkup link, *including* interwiki links, is treated as internal and escapes.
This is correct.
(This has caused much elaborate conspiracy theory in the past revolving around nofollow and "favoured" Wikia links, etc)
As is this.
