Hmph. My knee-jerk reaction was that it is utterly disgusting if we
quote when we do NUL-terminated. Is your "quoting is OK over NUL
terminating" because "-z" applies only to the input? If so, then I
would agree that is OK, but shouldn't the quoting apply regardless
of how the input is formulated? Why do we call the cquote helper
only under "-z"?
