The elisp ref says:

 -- Variable: list-buffers-directory
     This buffer-local variable specifies a string to display in a
     buffer listing where the visited file name would go, for buffers
     that don't have a visited file name.  Dired buffers use this

and that's how list-buffers, ibuffer and now bs use it. It makes sense.

I think uniquify should use another variable.

The way it is used (other than in uniquify), it's more of a directory
than a filename, I think. buffer-working-directory, something like
that, perhaps.
