[PATCH v3 5/5] emacs: Use message-cite-original in reply

[Adam Wolfe Gordon <awg+notmuch@xvx.ca>]

Use message-mode's message-cite-original function to create the
quoted body for reply messages. In order to make this act like the
existing notmuch defaults, you will need to set the following in
your emacs configuration:

message-citation-line-format "On %a, %d %b %Y, %f wrote:"
message-citation-line-function 'message-insert-formatted-citation-line

The test has been updated to reflect the (ugly) emacs default.
---

Here is an alternate version of the patch, which uses message-cite-original.

I suggest people try out this version and see if the behavior is
acceptable with some configuration tweaks. If it is, then we can
work on implementing the notmuch-emacs config file idea, and go
with this version. As I mentioned, the one thing I haven't figured
out how to do with configuration is make message-cite-original fill
the quoted message. This would probably be a dealbreaker for me, but
I suspect it can be done somehow with the right combination of hooks.
