Thank you so much for looking further into this. Your reasoning &
questions above seem exactly right to me. Knowing this
"combination of the 'larger' functions, invoked properly" would be
a good thing, and I think might be of general utility in the Gnus
code. Surely this isn't the only place where a group needs to be
told that its article set has changed and that it needs to refresh
itself in a local-only way.
By the way, I received your message twice, with two separate
Message-ID headers:
Message-ID: <87v97zsfod.fsf@ericabrahamsen.net>
Message-ID: <87tunjsfnm.fsf@ericabrahamsen.net>
Letting you know just in case that's a manifestation of some kind
of message-sending buglet. (Since I was an explicit recipient in
the headers, along with emacs-devel, I wondered if maybe your MUA
or MDA somehow generates a distinct message, with its own
Message-ID, for each recipient, instead of all recipients getting
the same message.)
Best regards,
-Karl
