I looked at this and I have a few comments:
        1) What is the point of PROCINFO["FS"]?  Isn't it equivalent to
           just checking to see if FIELDWIDTHS is set or not?  (Well, I
           guess in the pathological case where you assign a null string to
           it, but, really, does that matter?)
        2) I think the real problem is that setting the variable via the
           "-v" command line option, doesn't trigger the normal
           re-evaluation.  I'm wondering if that wouldn't be the better
           place to fix this.
