Too bad.  I thought that it would be easy (at least for headlines) by
simply allowing `comment-start' before the headline.

The problem with this is, that "with text" will be commented, too.  But
in my case this would be source code, which should not be commented.

So now I think I'll stay with outline-minor-mode.  The thing which is
much better with orgstruct-mode is that TAB has a special meaning
depending on the context point is on.  So I'll use that feature to make
outline-minor-mode do what I want.  IMO this facility could be of use in
may other places, too.  I think it would be nice to rip that out of
org-mode into something more generic, like

  (define-context-key some-keymap (kbd "TAB")
                      'foobar-context-p
                      'do-foo).

I played a bit with the code and tried to elicit how you get the command
that normally would have been invoked if the stealing function wasn't
there, but I failed.  Could you please enlighten me?

All the best,
