[O] Bug: bulk TODO state change creates a LOGBOOK state change note only for one task

[Maxim Baz]

The important piece of org-mode configuration is:

    org-minimal.el

    (setq org-todo-keywords '(

      (sequence "TODO(t)" "NEXT(n!)" "|" "DONE(d)")))

So I expect the following note to appear in LOGBOOK once I change the state from TODO to NEXT:

    :LOGBOOK:

    - State "NEXT"       from "TODO"       [2015-02-04 Wed 22:11]

    :END:

It works perfectly fine if I change a state of a single task. 

But if select multiple TODO tasks in Agenda view and change all of them to NEXT in bulk, only the last task will have such "state change" record.

I expect org-mode to create such "state change" note in LOGBOOK drawer for every task I'm changing.

Now I'll describe my steps in a bit more detailed way, and afterwards you will find the system information I use.

1. emacs -Q -l ~/org-minimal.el ~/test.org

2. Create 3 tasks: 

    * TODO task1

    * TODO task2

    * TODO task3

3. M-x -> org-agenda-file-to-front

3. M-x -> org-agenda -> t

4. Mark those 3 tasks

5. M-x -> org-agenda-bulk-action -> t -> NEXT

The ACTUAL contents of ~/test.org is:

    * NEXT task1

    * NEXT task2

    * NEXT task3

    :LOGBOOK:

    - State "NEXT"       from "TODO"       [2015-02-04 Wed 22:11]

    :END:

The EXPECTED contents of ~/test.org is:

    * NEXT task1

    :LOGBOOK:

    - State "NEXT"       from "TODO"       [2015-02-04 Wed 22:11]

    :END:

    * NEXT task2

    :LOGBOOK:

    - State "NEXT"       from "TODO"       [2015-02-04 Wed 22:11]

    :END:

    * NEXT task3

    :LOGBOOK:

    - State "NEXT"       from "TODO"       [2015-02-04 Wed 22:11]

    :END:
