There is a set of patches in the queue to add a JSON output format for
reply, with the emacs UI then consuming that to construct the reply
template [0].  This will make it very easy to communicate to the emacs
UI that the original message was encrypted, and that the reply should be
similarly encrypted.  I'm going to wait until that patch set makes it
through, and then build this functionality on top of that.
