I took a look at hl-line-mode implementation and the solution is very
simple. It puts an overlay onto the whole line including the newline
character (note the 1+):

      (move-overlay hl-line-overlay
                    (line-beginning-position) (1+ (line-end-position))

I also tried it with text properties and it works the same way:

   (put-text-property (line-beginning-position) (+ 1
                     'face 'highlight)

I thought I finally found something which emacs couldn't do, but I was
wrong. Emacs cannot be beaten. :)

The only thing remaining is to hack outline mode somehow to propertize
headings this way. I think it's an improvement, so it should  be
included (with an option maybe) in the default outline.el.
