So, the much earlier work-around and related text adjustments and such
for the email interface to mailman
https://lists.balug.org/pipermail/balug-admin/2017-July/000846.html
no longer needed with the problematic eximconfig stuff gone.
So, basically reverted those changes (work-around descriptive
text in messages, etc., where it was applicable).  Much clearer now,
and mailman commands can now be done fine in the Subject: header
with an empty email body.
