RE: single pass pem-mime

Personally I find that the single pass code to process
MIME such as metamail is a bit of a mess. I prefer to have a first pass
that parses the message and returns a structure. Then you pick the bits
of the structure that you want. 

I would rather NOT see changes made just for the sake of single pass
parsing. Having as little clutter at the top of the file for NON-MIME
and PEM users is a good idea.

Better to have 
        Hmm, wonder what this PEM stuff is about 
instead of

        B****y PEM users...
