Surprised I was not.

Yes, I find it frustrating to read Gmane-era list messages.

But now these references are already forever in the Git history. So even
if I end up obfuscating them with a URL encoding, it will be clear from
the history... for those who go to the trouble of looking.

But see later in this message about how to retain the original msg-ids.

Yeah I suspected that email-only users would have such a slick
setup. Thanks for explaining.

What if we used footnotes for all of the original msg-ids?

    <URL>[1]

    [...]

    [1]: <msg-id>

Or maybe just for the ones that need URL encoding? I personally think it
would be better to use them for all if we go for this approach.
