 395                The important thing to know is that odd numbers are considered
 396                good, while even ones are considered errors.
 397      Bits 3-15: actual status number
 398      Bits 16-27: facility number.  0 is considered "unknown"
 399      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
 400                  output the message (which, for random codes, just looks ugly)
 401
 402      So, what we do here is to change 0 to 1 to get the default success status,
 403      and everything else is shifted up to fit into the status number field, and
 404      the status is tagged as an error, which I believe is what is wanted here.
