[O] Bug: Non buffer-local org-not-done-heading-regexp breaks TODO dependencies under certain circumstances [8.3beta (release_8.3beta-1178-g317886 @ /opt/local/share/emacs/site-lisp/org/)]

[Alexander Borkowski]

Hi all,

I experimented a bit with per-file TODO keywords and noticed that
under certain circumstances TODO dependencies are broken. A minimal
example to reproduce the problem I encountered (under emacs -q)
would be as follows:

- Enable TODO dependencies, i.e. eval

(setq org-enforce-todo-dependencies t)

in *scratch*.

- Create one file (e.g. "~/test-local.org") with these contents:

#+TODO: LOCALTODO | LOCALDONE
* Local Parent
  :PROPERTIES:
  :ORDERED:  t
  :END:
** LOCALTODO First
** LOCALTODO Second

Then add it to the end of agenda-files (with C-u C-c [) and close the buffer.

- Create another file (e.g. "~/test-global.org") with these contents:

* Global Parent
  :PROPERTIES:
  :ORDERED:  t
  :END:
** TODO First
** TODO Second

Then also add it to the end of agenda-files (with C-u C-c [) and close the 
buffer.

- Now view the global TODO list (M-x org-todo-list) and notice that the second
TODO from the "local" file is not dimmed and it is possible to change its TODO
state (using the t key) as it is not blocked, but should be.

I did some tracking down and I think this comes from the fact that variable
org-not-done-heading-regexp is not buffer-local. It probably should be as both
lines 4800 and 4803 in org.el are:

(make-variable-buffer-local 'org-not-done-regexp)

When I re-open emacs and eval (what I suspect line 4803 should be)

(make-variable-buffer-local 'org-not-done-heading-regexp)

in *scratch* before re-runing the above steps everything works as expected.

Regards,

Alex B.
