Those comments were stripped from the function bodies because they already are
present in their leading comment blocks. Leaving them there sounded to me just
like echoing the very same thing twice.

However, each one of those functions is just called once from ad_mux_machine(),
so it might be a better idea (and easy) to wipe them away -- following your
suggestion a); or we can just leave them there, turning them into inline
functions instead. What approach do you prefer?

All other notes and suggestions you provide me will be accomplished soon.

Thanks for keep providing valuable feedback.

Cheers!
