When showing a message, if the user doesn't specify --decrypt= at all, but a stashed session key is known to notmuch, notmuch should just go ahead and try to decrypt the message with the session key (without bothering the user for access to their asymmetric secret key). The user can disable this at the command line with --decrypt=false if they really don't want to look at the e-mail that they've asked notmuch to show them. and of course, "notmuch show --decrypt" still works for accessing the user's secret keys if necessary.
