I went for a similar idea, though my ancient pick has no -noseq.  Then I
plumped for bash to get pipefail, aiming to have $? be non-zero if the
sequence doesn't exist, e.g. there's no current message.

    #! /bin/bash

    set -eEu -o pipefail

    (($#)) || set cur

    scan -format '%(msg)' "$@" |
    while read n; do
        yes n |
        repl -cc all -query -editor false $n 2>/dev/null || true
    done |
    sed -r 's/\<Reply to ([^?]+)\? /\1\n/g'

BTW, from testing I find it annoying that `mark -s cur -d cur' gives no
error and $? is 0 yet cur remains set.  What benefit does this have, I
wonder?

Cheers, Ralph.
