Isn't that an implementation detail, as far as the current discussion is 
concerned? Git can also show only the status of files in a subdirectory, 
if you ask it.

You've missed http://debbugs.gnu.org/12492, then. This patch also 
constitutes one request, obviously.

And you shouldn't forget that VC is not the most popular VCS package 
among advanced Emacs users, Magit is. We're playing catch-up.

That's an awkward proposal. To have to open vc-dir, then move my hand to 
the mouse, or point to the button, then push it...

Root is a good default, so vc-dir buffer for it should be easier to 
create than for a subdirectory.
