It is the underlying Python email library that folds the Subject:
header and determines where to fold. You could argue that it shouldn't
give preference to foldable whitespace following a comma or semicolon
in the unencoded value of the subject as these aren't syntactically
significant in a subject, and that may be valid, but it is still
folding in a standards compliant manner.

I would argue that Eudora is much more at fault here for not unfolding
the subject before presenting it in its TOC.

What does Eudora do with RFC 2047 encoded Subject: headers such as the
example in section 8 of the RFC

If Eudora would unfold the header before putting as much as fits into
the subject field of its TOC, this wouldn't be an issue. From my point
of view, you're asking that Mailman, which is already standards
compliant, alter its behavior to compensate for a non-compliant MUA.

No. I think that this would require modifying the Header module in the
Python email library.
