Re: A way for interactive to modify a let-bound variable?

I am happy that it works and much much better than my first version (
https://github.com/kaushalmodi/.emacs.d/blob/0b427ce554b1cade7f5fabb8ee4bfb704f6e497f/setup-files/setup-editing.el#L686-L730
).

I just wanted to go an extra mile and prevent the duplication of the
conditions.. first time in the interactive form for settings the fn args
and second time when deciding when to display the message. I just wanted to
check if the "extra optimization" I thought of was possible. So the gist
is.. what happens in interactive stays in interactive. :)

Thanks.
