`mhshow -type text/plain -type image/png' should show no parts except
those two.  And if there's a multipart/alternative and it contains both
of those then the normal multipart/alternative rule applies;  the sender
ranked them by order and I get just one or else I'd see duplicate
content.

I have wanted to store both text/plain and text/html from a folder of
emails on a regular basis so someone else can browse them, and used two
mhstores to do so.  That comes back to an `all alternatives' switch.

Cheers, Ralph.
