How does the Parser recognize whether or not an article title containing a slash is a subpage or a normal top-level article?
For example [[Nip/Tuck]] (a U.S. television show) in Wikipedia does not generate an automatic "upward" link to the [[Nip]] article (which exists), as it would if it were a subpage.
There's a global setting for which namespaces to perform subpage processing in; article namespace is excluded.
