Well, that's an earful. Faced with this authoritative opinion, I
withdraw my previous objections to changing the output format for CIDR.
It would seem that the appropriate behavior would be to make the default
display format for CIDR be like "10.0.0.0/8". Now the text() conversion
function already produces this same format. I'd be inclined to leave
text() as-is and add a new conversion function with some other name
(suggestions anyone?) that produces the shorthand form "10/8" as text,
for those who prefer it.
Comments?
