[PATCH] emacs: Add commentary for MELPA users

[David Bremner]

We have a steady trickle of people using notmuch-emacs from melpa with
distro packages of notmuch, and then being confused when it doesn't
work. Try to warn people what a foot-gun this is; this commentary
should be copied to the melpa web site.

+;; Note for MELPA users (and others tracking the development version
+;; of notmuch-emacs):
+;;
+;; This emacs package needs a fairly closely matching version of the
+;; notmuch program. If you use the MELPA version of notmuch.el (as
+;; opposed to MELPA stable), you should be prepared to track the
+;; master development branch (i.e. build from git) for the notmuch
+;; program as well. Upgrading notmuch-emacs too far beyond the notmuch
+;; program can CAUSE YOUR EMAIL TO STOP WORKING.
+;;
+;; TL;DR: notmuch-emacs from MELPA and notmuch from distro packages is
+;; NOT SUPPORTED.
