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
