Thanks for your reply (and the others, too).

This very thread is broken for me.  Looking at your reply, I see
the references header contains

<mailman.15146.1131928411.20277.info-gnus-english@gnu.org>

But the Message-Id of my original post was

<87d5l4oyph.fsf@gmail.com>

Why?  Does mailman rewrite the Message-Id?  Any way to prevent that?
