Note that the MM 2 list footer had somewhat different content, but the
same structure as this one.

In any case, if there is consensus that the 'line' at the beginning of
the footer should be changed to a '-- ' separator, I can do that. Let me
know.

Here's more detail.

This gets very tricky. If the original post is a simple text/plain
message, Mailman will just append the footer to the message body. In
that case, if the original had a signature with a '-- ' separator and
the footer also had one, Thunderbird treats everything from the first
separator on as a signature block. I didn't check any other MUAs.

However, if the original post is more complicated such that after
possible content filtering (not done on this list) it is other than a
simple text/plain message, the footer is added as a separate MIME part.

For example, the message to which I'm replying had the original structure

multipart/alternative
    text/plain
        plain text alternative
    text/html
        rich text alternative

and the post delivered from Mailman had the structure

multipart/mixed
    multipart/alternative
        text/plain
            plain text alternative
        text/html
            rich text alternative
    text/plain
        the footer

There is much variation in how different MUAs render that.
