But if I do that somewhere in the middle of write_header, then I still
cannot be right all the time because the length varies depending on
seen_subj. It would be better if either

a) a Subject: line was inserted already in bogoreader if it's missing

or

b) a flag got set during reading that no Subject: line is present (I'm
   however not sure whether this would work for mailboxes and not only
   for single mail messages).

Of course, we're only talking about passthrough mode here.

Any ideas?
