Yes. :-P
At least that is what I was aiming for.

In particular, if none of -y, --no-prompt or --prompt is passed on
the command-line, I don't want to set either key in the hash.
(Or, to put it another way, I don't want to change the behaviour
in this case, where neither variable is set in the environment
of the helper script)

ATB,
Ramsay Jones
