Enclosed is a patch to provide "hit any key" prompts when displaying multipart
mime messages. In certain contexts, which have become common now that I use
-attach, I really don't like the default "Press <return> to show content"
behavior.
If someone is willing to fold this into the source, please let me know and
I'll add --enable-noncanonical-prompts-for-multipart-mime-messages or somesuch.
