Sometimes I receive "multipart/alternative" messages, where "text/plain" part
is either empty or tells to read the message using an html capable mail reader.
Here is an example of vm-list-mime-part-structure on such a message:
("multipart/alternative" "boundary=----=_Part_8316_1598440439.1540713452805")
("text/plain" "charset=UTF-8")
("text/html" "charset=UTF-8")
How can I in such a situation tell vm to display the "text/html" part? I don't
want to see the "text/html" part automatically for every message, but only if I
have to.
