+Fix to automatically wrap long headers (for RFC compliance) before
+sending. This should probably just be fixed in message-mode itself,
+(but perhaps we can have a notmuch-message-mode that layers this on
+top).
+
+Implement Fcc and use it for all messages, (whether a new composition,
+a reply, or a forward). This again may require a notmuch-message-mode
+that extends message-mode.
