I recently upgraded to the newer notmuch to test out the new folder
patch (its great!) and the new decryption/signature verification (its
fantastic!), and noticed something odd start happening.

I think that notmuch moves a new message to the maildir cur directory,
From the new directory when you first read it. Is that right? This is
actually what I would expect with maildirs, but notmuch wasn't doing
this before.

The reason why I care is because if I open a message,
notmuch-show-get-filename tells me that the file is located in the
'new/' path, but it is actually not there at all, looking around it
appears to be in the 'cur/' directory. 

This is because I made a function to let me do bayes training by putting
mistaken emails in my Mistakes folder, so that they can be retrained:

(defun notmuch-mark-as-mistake ()
"Moves the current message into the Mistakes folder"
  (interactive)
(let* ((fullpath (notmuch-show-get-filename))
      (filename (file-name-nondirectory fullpath)))
      (save-excursion
(rename-file fullpath (concat "/home/micah/Maildir/INBOX.Mistakes/new/" filename)))
(notmuch-show-archive-thread-then-exit)
(notmuch-search-refresh-view)
(hl-line-mode 1)(hl-line-mode 1)))

(define-key notmuch-show-mode-map (kbd "S") 'notmuch-mark-as-mistake)

if I hit the 'S' key on a message now, it complains that it cannot
rename the file because it doesn't exist.

Incidentally, does anyone know how I can do this without having to
actually do a notmuch-show on the message? Most spam I can recognize by
the subject in my inbox, and I dont need to open it to see that.
