Mailman blows away <x-flowed>

[Daveyost]

Somebody replies to a list message, with To going to a me, and Cc going to
the list.

The former has this body:

<x-flowed>

</x-flowed>

Whereas the latter has this body:

Mailman is not doing this unless the original message contains alternative
parts and content filtering is removing the part with <x-flowed></x-flowed>
tags.

Under some circumstances, Mailman will remove an RFC 3676 Format=Flowed
parameter from the Content-Type: header. This is bug #1495122
<https://sourceforge.net/tracker/index.php?func=detail&aid=1495122&group_id=103&atid=100103>.

If some MTA/MDA/MUA is generating the <x-flowed></x-flowed> tags from the
Format=Flowed parameter, then Mailman could be indirectly responsible.
