I want it to work with M-x, C-u M-x, and C-u 100 M-x. Then I want the same defaults for interactive and non-interactive use.

That's no accident. Oh, there are long sequences setting up the interface in the Emacs source alright. Sometimes they are so long they have become separate functions of their own. -- underground experts united https://dataswamp.org/~incal
