This mail id:1405026779-29966-1-git-send-email-tomi.ollila@iki.fi
has not got much attention, probably due it is marked as 'draft'
and as it was not marked 'needs-review' in nmbug (this is now changed).

As the script is IMO in good condition (is IMO feature-complete and robust)
the draftness comes from the commit message being blunt and the namual .rst
not (yet updated).

I've been using this version like 3-10 times per week for quite a long time
now. I normaly use the -nw, --to, --subject and --body options to send
work-related mail. Just yesterday I was planning to also use the --from
option to send email on (mutually agreed) behalf of a colleaque...

This is somewhat more complex than the older alternative at
id:1404244957-3671-1-git-send-email-david@tethera.net, but addresses
the comments I sent in id:m2k37thvq1.fsf@guru.guru-group.fi .

I think the script is straightforward enough for anyone who knows 
shell scripts a bit more than just the shiny surface ;)

This script also handles mailto: urls -- I just set firefox to run
this script on mailto: links and (in my case) emacs in my X desktop
appears with Message buffer filled with initial contents as expected.
If mailto: link had body content, then Message buffer was in modified
state (otherwise not!), which is a bit PITA to exit in case of accidental
clicks. I have a potential "fix" for that in a diff that otherwise contains
comment changes below -- whether the fix should be applied is a bit
controversial -- is there a chance that some other buffer is set to
non-modified state; I tried with emacsclient(1) interface (too) and
right buffer was set to non-modified state in this case too...

If users are interested to have this version of notmuch-emacs-mua
available in future notmuch versions I'll update the manual .rst,
pick David's manual building change and write suitable commit message to 
the forthcoming patch email.
