               The important thing to know is that odd numbers are considered
	       good, while even ones are considered errors.
     Bits 3-15: actual status number
     Bits 16-27: facility number.  0 is considered "unknown"
     Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
                 output the message (which, for random codes, just looks ugly)

     So, what we do here is to change 0 to 1 to get the default success status,
     and everything else is shifted up to fit into the status number field, and
     the status is tagged as an error, which I believe is what is wanted here.

	259	The important thing to know is that odd numbers are considered
	260	good, while even ones are considered errors.
	261	Bits 3-15: actual status number
	262	Bits 16-27: facility number. 0 is considered "unknown"
	263	Bits 28-31: control bits. If bit 28 is set, the shell won't try to
	264	output the message (which, for random codes, just looks ugly)
	265
	266	So, what we do here is to change 0 to 1 to get the default success status,
	267	and everything else is shifted up to fit into the status number field, and
	268	the status is tagged as an error, which I believe is what is wanted here.
