 406                The important thing to know is that odd numbers are considered
 407                good, while even ones are considered errors.
 408      Bits 3-15: actual status number
 409      Bits 16-27: facility number.  0 is considered "unknown"
 410      Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
 411                  output the message (which, for random codes, just looks ugly)
 412
 413      So, what we do here is to change 0 to 1 to get the default success status,
 414      and everything else is shifted up to fit into the status number field, and
 415      the status is tagged as an error, which I believe is what is wanted here.
