Comment 7 for bug 373083

Mark, I attach a new patch to solve the problem. It only keeps CTE for the message-charset.
Petr, mailman's behaviour for adding header/footer have been the same for more than 4 years. No one cared this until I needed this charset adjustment feature other than Japanese. Changing the default behavior may cause unwanted trouble. So, let's keep the default charset order at least in mailman-2.1 and cosider changing in 2.2.

Note that the order is configurable in mm_cfg.py with this patch.
