I like that. He (Jay) also writes:
>yes: pipe the output to some other program that expects 'y' or 'n'.

#!/bin/sh
# yes - be repetitively affirmative

case $# in
0) set y;;
esac

exec sed '
: again
p
b again' <<EOT
$1
EOT

Now there is still nroff to take care of. Anybody feels an urge to
add his "one"-liner, using sed 8-) ?
