Good!  You're considering the various additional complications.  I think
it's going to get messy :-(

The firstline flag will need to be initialized with each message.  The
corrected length will need to use the seen_subj flag.  You'll also need
to allow for spam_subject_tag, unsure_subject_tag, and the X-Bogosity
line.  

If you force passthrough mode to keep the message in memory, it might
make it easier.  That would give you access to all the lines, allow
changes, counting characters, etc.
