Hm.  On inspection, you're right.  Looking at the history, I used to have it
doing tree traversal, then discovered I could get rid of that necessity by 
removing the -l option from the command.

And now they are in fact the only backends doing that.

I think this is no longer true.  I looked for directory-files throughout
the VC files; none of the uses are within vc-dired-hook anymore,
except in Arch where they're necessary because of the odd way Arch
represents working-directory state.

So I think we've actually achieved what you want.

Not unless we want to wire an equivalent back into speedbar.el.
It's also genuinely needed in vc-next-action.
