There are often different ways to look at it.  E.g. Let's say that
a mode displays two columns of text and set tab-width to half-the
window-width for that purpose; is it "using" tab-width?  I'd say yes.

Similarly, I tend to think that PCL-CVS "uses" list-buffers-directory in
order to improve the behavior of uniquify.

In general, variables are a means of communication, and each side of
the communication thinks of itself as "using" the variable and the other
side(s) as "providing" the variable.

If you don't want to get rid of it, then I think it's worthwhile to
improve it and mention that it is used also (on the other side) by
list-buffers and by uniquify.
