I wonder if there is a wiki engine that uses markdown

Did you had to extend the syntax with non-standard extension to deal with the specific needs of a wiki engine?

Gitit handles wikilinks by overloading normal link syntax: links with empty URLs become wikilinks. So, [My page]() is a wikilink to the page called My page. The transformation can be done either on the AST or in the renderer. This approach saves having to invent an entirely new syntax for wikilinks.
