> What's wrong with the same technique, i.e. using font-lock-fontify-region?

For my keyword rules I almost never set the "override" element to t 
So if i use a first keyword that set all the entire region (".*") to a face that set the background, the other rules won't work.

An other issue with this kind of "background rule", my code that shows the whitespaces would not work either.

Is it possible for a (point) in the buffer to have a face and a background color that is different from the background property of the face ? This way I would be able to set the background of the region and after that play with faces.
