* mu4e-compose.el: let message-mode FCC take care of saving to sent-messages
- replace the old system with a bit less rube-goldbergesque (only a bit)
system. Immediate advantage is that attachments are now also present in
the saved messages, i.e. the copy is now the /same/ as what is sent,
rather than an approximation.
'fcc' refers to saving a copy of a sent message to a certain folder. that's
what these 'Sent mail' folders are for!
We let message mode take care of this by adding a field
Fcc: <full-path-to-message-in-target-folder>
in the "message-send-hook" (ie., just before sending).
message mode will then take care of the saving when the message is actually
sent.
note, where and if you make this copy depends on the value of
`mu4e-sent-messages-behavior'.
- also quite a bit of cleanup in particular on mu4e~compose
