Thank you a lot, I studied the diff you made, and I will try to improve
:)

For persistent_add, nothing. It just marks that the variable is from now
on persistent. If you do config_query* on that variable, and it was
not persistent allready, it's value will be first cleared. (this way we
stop the leaking). If it was persistent allready, nothing special
happens.

What a question :) OPTS is generated each time spell is casted, so I
don't see reason to make it persistent. You can do this:

config_query SCREW "Do you want to make casting interesting ?" ?
[ SCREW == 'y' ] && OPTS="$OPTS --screw-it"

This way the qestion is remembered for next casts, and OPTS is not made
persistent.
