DOS feature on formatting disk

Hi Randy
 I've written special drivers for the floppies
under DOS in the past so that isn't a real
issue. I just wish it would work without me
having to pull out the reference books to
deal with it.
 It works incorrectly in both MSDOS and PCDOS.
It is just annoying. The /u should mean just that,
unconditionally format.
