You can use `text' to mean the width of the text area, AFAIK.
Subtract the width of the text you want to display from it, and you
have your WIDTH.  Would that do the trick?

Alternatively, maybe `(space :align-to (- right-fringe 9))' will do
what you want?  (9 being the number of characters in "#XXXXXX " that
you want to end at the right margin.)
