[Wikipedia-l] yay subpages, finally!

It does, in the current implementation (however, if "GNU" does not exist,  
it does not add a backlink). This was necessary to "grandfather" existing  
subpages, as Zoe put it. The alternative would be to use another magic  
character which is currently not allowed in titles, to add an is_subpage  
flag, or to use a more complex logic that does not store the parent page  
in the title.
