Hi Nicolas, hi all

The help provided from this thread about the function outline-level
and "Match Data"
http://thread.gmane.org/gmane.emacs.orgmode/42611
allowed me to make the attached patch. It resolves two or so buglets,
the one I found first was introduced by
http://orgmode.org/w/?p=org-mode.git;a=commitdiff;h=ddc24673877da5f7d82375fb10b8cc238e2ff6a7
according to git bisect.

Michael

I would happily apply your patch, but could you explain, before, what
bugs are solved by it ? Thank you.

BTW, your bugfix commit mentioned by me was not buggy at all, it just
unleashed (before I wrongly wrote "introduced") this buglet hidden
before: "C-c *" on an item inside heading and only with "odd":
#+begin_src org
  ,#+STARTUP: odd
  ,* section
  ,  - item
#+end_src
expected: 3 stars, buglet: 2 stars

The second buglet, found in the source code while resolving the first:
"M-1 C-c *" on an item before first heading:
#+begin_src org
  ,- item
#+end_src
expected: 1 star, buglet: 2 stars

According to my understanding of the source code of org-toggle-heading
I expect no other buglet with "C-c *" on items or body text. At least
I found no buglet left when testing my changes with the necessary
combinations to cover all 4 cases within each of both "cond" and both
"if nstar" in the source code region I changed:
- no region / region with body text lines or one item nested in one item
- item(s) / body text line(s)
- before first heading / inside heading
- "C-c *" / "M-1 C-c *" / "M-2 C-c *"
- #+STARTUP: oddeven / odd
Quite a rigorous testing :-)

Michael

This is clearer now. Thanks for the examples and the patch. I have now
applied it.
