(Including list in reply)

Well, judging by the subject in your reply to me, your MUA does the
right thing, with Subjects that begin with Re:

But there are other issues here. The example above is from a list at a
site which has configured

OLD_STYLE_PREFIXING = No

So that Mailman puts the subject_prefix ([Bar]) at the beginning of the
Subject: so a list post will be distributed with a Subject: like

Subject: [Mailman-Users] Re: Multiple "Re:" in subject

rather than

Subject: Re: [Mailman-Users] Multiple "Re:" in subject

With this subject, a replying MUA probably creates the subject like

Subject: Re: [Mailman-Users] Re: Multiple "Re:" in subject

but Mailman has logic in the subject prefixing code to remove redundant
Re:, Aw:, Sv: and Vs: from the beginning of the subject in this case so
Subject: headers with multiple Re: such as your example should not be
occurring, however there appears a bug in that code. It will remove all
the redundant Re:s from

Subject: Re: [Bar] Re: Re: Re: Re: Re: Re: IMP tice

but not from

Subject: [Bar] Re: Re: Re: Re: Re: Re: IMP tice

I will fix it.
