[PATCH] cli: add a tool for starting new message in the emacs ui

From: Jani Nikula <jani at nikula.org>

Add a tool to start composing an email in the Notmuch Emacs UI with
the specified subject, recipients, and message body.
---

I added the necessary lines to conf.py to get the man pages built and installed

I'd be happier with this if it could start emacs. I tried adding "-a
''" to the emacsclient invokation, but that doesn't quite work; the
message-mode buffer is created in emacs but no frame is displayed. It
could be a peculiarity of my emacs setup, of course.

+notmuch-emacs-mua
+=================
+
+SYNOPSIS
+========
+
+**notmuch-emacs-mua** [options ...] [<to-address> ...]
+
+DESCRIPTION
+===========
+
+Start composing an email in the Notmuch Emacs UI with the specified
+subject, recipients, and message body.
+
+For **notmuch-emacs-mua** to work, you need **emacsclient** and an
+already running Emacs with a server.
+
+Supported options for **notmuch-emacs-mua** include
+
+    ``-h, --help``
+        Display help.
+
+    ``-s, --subject=``\ <subject>
+        Specify the subject of the message.
+
+    ``--to=``\ <to-address>
+        Specify a recipient (To).
+
+    ``-c, --cc=``\ <cc-address>
+        Specify a carbon-copy (Cc) recipient.
+
+    ``-b, --bcc=``\ <bcc-address>
+        Specify a blind-carbon-copy (Bcc) recipient.
+
+    ``-i, --body=``\ <file>
+        Specify a file to include into the body of the message.
+
+    ``--print``
+        Output the resulting elisp to stdout instead of evaluating it.
+
+The supported positional parameters and short options are a compatible
+subset of the **mutt** MUA command-line options.
+
+Options may be specified multiple times.
+
