this works for me:
 /bin/busybox | sed -e '1,/^Curr/d' -e '/^$/d' -e 's/,//g'

(i don't know why you say it goes to stderr -- it doesn't.  i see
in your message that it's using printf.

i have no objection to what you're proposing, if people really
want it.  but i'd imagine what they really want to know is if a
particular applet is present, in which case they'll be filtering
the output anyway, and there's no big difference between this:

   busybox | grep -q myapplet && echo "it's there!"

and doing the same thing with "--list"
