   Try the patch below.  It:
   - allocates an extra byte to each column
   - will flip to one line per disk if there are too many disks (and the
     screen has spare lines)
   - will flip back as well (shrink screen to < 24 lines)
   - actually clears the old text when a disk is removed (:del xx0)
   
   Note that mode switch is deferred until the next refresh.
   (maybe I should decide the mode while displaying the titles)


i think it looks good; i can't compile it on my raid system easily
but it seems to work fine.
