Thank you for this. I had tried to reroll your patches
(id:"1326826969-23545-1-git-send-email-jrollins@finestructure.net") on
top of 0.12 and that was a miserable failure, so the above works
well. In fact, I have made it like this instead:

(define-key notmuch-show-mode-map "d"
  (lambda ()
    (interactive)
    (notmuch-show-tag-message "+deleted")
    (notmuch-show-next-open-message)))

... but it doesn't seem to actually go to the next message... oh well,
at least I can delete mail.

Also note that you can delete whole threads with this:

(define-key notmuch-search-mode-map "d"
  (lambda ()
    (interactive)
    (notmuch-search-tag-thread "+deleted")
    (notmuch-search-next-thread)))

... and I have added an undelete function:

(define-key notmuch-search-mode-map "u" 
  (lambda ()
    (interactive)
    (notmuch-search-tag-thread "-deleted")
    (notmuch-search-next-thread)))

I use this script:
