digest_payloads() looks for quoted-printable in Content-Type … ?

[FGasper]

In digest.py there is logic to look for an indication of quoted-printable encoding in the charset attribute of a message part’s Content-Type. As best I can tell, that information is always sent in the Content-Transfer-Encoding header, though. There doesn’t seem to be anything in this module that checks this header.

Is that part of digest.py “dead” logic? Or is there some mailer out there that actually indicates the transfer encoding in the Content-Type header?
