I did copy the =b/=B. I hadn't considered IMAP for this feature, as I'm
not using it. Since we have to parse the message to match content-type,
how would this behave under IMAP? Would it work on the server, or
does it have to be local? If it can work on the server, then perhaps I
should distinguish that -- I can imagine an IMAP user might not want to
download large PDF-containing messages while performing this limit.
I'll remove the =M lines for now.

Fixed.

Looks like mutt_parse_content_type() always sets subtype to
a non-NULL value. Check has been dropped (and it was
in the wrong place anyway, since by this point it's baked
into buffer).
Updated patch attached.
