421      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
422                  output the message (which, for random codes, just looks ugly)
423 
424      So, what we do here is to change 0 to 1 to get the default success status,
425      and everything else is shifted up to fit into the status number field, and
426      the status is tagged as an error, which I believe is what is wanted here.
