-;;; Commentary:
-
-;; In this file, various functions to compose/send messages, piggybacking on
-;; gnus' message mode
-
-
-;; Magic / Rupe Goldberg
-
-;; 1) When we reply/forward a message, we get it from the backend, ie:
-;; we send to the backend (mu4e-compose):
-;;     compose type:reply docid:30935
-;; backend responds with:
-;;      (:compose reply :original ( .... <original message> ))
-
-
-;; 2) When we compose a message, message and headers are separated by
-;; `mail-header-separator', ie. '--text follows this line--. We use
-;; before-save-hook and after-save-hook to remove/re-add this special line, so
-;; it stays in the buffer, but never hits the disk.
-;; see:
-;;     mu4e~compose-insert-mail-header-separator
-;;     mu4e~compose-remove-mail-header-separator
-;;
-;; (maybe we can get away with remove it only just before sending? what does
-;; gnus do?)
-
-;; 3) When sending a message, we want to do a few things:
-;;   a) move the message from drafts to the sent folder (maybe; depends on
-;;      `mu4e-sent-messages-behavior')
-;;   b) if it's a reply, mark the replied-to message as "R", i.e. replied
-;;      if it's a forward, mark the forwarded message as "P", i.e. passed (forwarded)
-;;   c) kill all buffers looking at the sent message
-
-;;  a) is dealt with by message-mode, but we need to tell it where to move the
-;;     sent message. We do this by adding an Fcc: header with the target folder,
-;;     see `mu4e~compose-setup-fcc-maybe'. Since message-mode does not natively
-;;     understand maildirs, we also need to tell it what to do, so we also set
-;;     `message-fcc-handler-function' there. Finally, we add the the message in
-;;     the sent-folder to the database.
-;;
-;;   b) this is handled in `mu4e~compose-set-parent-flag'
-;;
-;;   c) this is handled in our handler for the `sent'-message from the backend
-;;   (`mu4e-sent-handler')
