We do know that a whole lot of people consider Magit to be the best 
thing since sliced bread. It does not provide such functionality, and I 
don't see anyone asking.

With prefix, it allows you to choose a different repository.

If the main purpose of vc-dir is to deal with modern systems better, we 
should better follow their conventions.

That's not good. 'C-u' should mean "I want to choose", and no prefix 
should mean "do the best possible thing", which is to use the repository 
root, since there's no obvious other choice.

I'd propose a patch like that, but vc-dir already changes behavior with 
prefix, and in a different way (allows to select the backend). Not sure 
how best to combine the two.
