618 which you are replying in an MH-Show buffer. Your draft, in

630 and choose one of its \"Automatically\" variants to do the same
631 thing. If you do so, the prefix argument has no effect.
633 Another way to include the message automatically in your draft is
634 to use \"repl: -filter repl.filter\" in your MH profile.
