There's a practical feature showing links to up-pages when on subpage:
eg. on page Wikipedia:Polls/2007/January you would see
< Wikipedia:Polls | 2007
if Wikipedia:Polls/2007 doesn't exist, you would see only
< Wikipedia:Polls
So this feature should behave same way:
eg. on page "Lorem ipsum (foo)" you would see link to "Lorem ipsum" (in case it exists)
bug 7264 may be considered as related since it will use same principle of cutting out the disambiguation part
