Looking at the sources, outline seems not to allow headlines with
whitespace at the beginning per default.

I think you could get it work, but you would have to modify some
variables like `outline-regexp' and `outline-heading-alist'.  Maybe it's
not worth the trouble if you are don't want to deal with internals.

I think that is a different issue.

I don't see this behavior here, neither with Emacs 23.3, nor with 24.
Does this happen with emacs -Q?  Which operating system do you use?

I wonder why you could hide such lines at all with outline-minor-mode.
I can't do that with the default setup.

Here is an example file with proper local variable settings that works
for me:


--8<---------------cut here---------------start------------->8---
* Headline1a
  ** H2a
  *** H3a
  *** H3b
  ** H2b

* H1b


Local variables:
outline-regexp: " *\\(\\*+\\)"
outline-level: (lambda () (- (match-end 1) (match-beginning 1)))
eval: (outline-minor-mode)
End:

--8<---------------cut here---------------end--------------->8---
