A backend implementation could use that logic, no problem.

As a VC API consumer, though, I don't really know, for an arbitrary VCS 
V, if the states that files can have in V, are:

- Fully represented by the list in `vc-state' docstring.
- All implemented by `vc-v'.

The backend may be ignorant of some of them, not all of which might be 
`ignored'.

And anyway, it's nice to be able to just call the function and filter 
the list passed to the callback by item states, and not have to 
implement set subtraction.
