outline-minor-mode-highlight really weird

[lisa-asket]

For me,  'append should not exist, but handled by (setq 
outline-minor-mode-highlight t)



Then, if you want outline-minor-mode to force its highlight on the major mode, 
use

(setq outline-minor-mode-highlight 'override).  



outline-minor-mode could call it (setq outline-minor-mode-highlight 'force) if 
that is more

understandable.  



Is there the possibility to use headings and keep the highlight of the major 
mode?

But for the others use that from outline-minor-mode.



At another level, how about having the possibility of using multiple 
outline-regexp

and for each be able to decide whether to override or not.  Currently there is 
only one 

highlighting setting for all regexp. 



What should be tackled first?

If the same region of text is highlighted both by the major mode and
by outline-minor-mode, the resulting colors will be different from
what you might expect, because Emacs will merge the two faces.

By highlighting the same parts of the buffer text. You basically tell
Emacs to use two different faces for the same text, so the result will
be the merge of the two faces.
