Could you remind me which behavior in 'M-n M-n' the aforementioned 
change relates to? Is this supposed to be like input history as well, or 
the contents of the completions table in a certain order?

I just tried find-file, and the future history is empty there, so I 
suppose this is something we added particularly for project-find-file.
