As a prototype try the following. This does assume that tagging
operations are fast enough not to be annoying interactively.

- customize notmuch-tagging-keys, add a key "m" to add tag "marked"
- customize notmuch-saved-searches, add a search "marked", for
   "tag:marked", with key "m".

- k m  to mark messages
- C-c j m  to bring up the list of marked messages
  - at this point you can unmark some by "k k m"
- finally * to apply "-marked +whatever"

The unpleasant part (IMHO) is having to specify "-marked" manually, but
that could be fixed by defining something like

(defun notmuch-tag-marked (tag-changes)
  "Add/remove tags from all messages currently tagged `marked'."
  (interactive
   (list (notmuch-read-tag-changes nil "Tag marked" "-marked ")))
  (notmuch-tag "tag:marked" (cons "-marked" tag-changes))
  (notmuch-refresh-all-buffers))

then define a key like

     (define-key global-map "\C-cm" #'notmuch-tag-marked)

I guess if people find this useful, we could add an appropriately
polished version. The main issue will me collisions with already
existing keybindings.
