I have a couple followup questions. In emacs, how can I run a query of
the form `notmuch search --duplicate=2 --output=messages '*''? I would
like to see messages with duplicates from with emacs. I looked at the
code for `notmuch-search' and could not find how to add the
`--duplicate=2' option.

I wrote a couple functions to easily switch between duplicates and show
the path of their files:

(defun my-notmuch-get-current-file-name ()
  (let* ((files (notmuch-show-get-prop :filename))
         (duplicate (notmuch-show-get-prop :duplicate))
         (curfile (nth (- duplicate 1) files)))
    curfile))

(defun my-notmuch-next-duplicate ()
  (interactive)
  (let* ((files (notmuch-show-get-prop :filename))
         (duplicate (notmuch-show-get-prop :duplicate))
         (newdup (if (= duplicate (length files)) 1 (+ 1 duplicate))))
    (notmuch-show-choose-duplicate newdup)
    (message (my-notmuch-get-current-file-name))))

I would like to add a function to call `rm' on the current file. What
should I do to make sure the change is picked up by notmuch? Run
`notmuch new' (I would do this from within emacs).

Thanks!
