See http://patchwork.newartisans.com/patch/581/ for a full diff. You can see I
only add *one* overlay: for the background face.

I'm surprised. Good to hear, but as some were finger pointing the overlays,
and as I added one for every block... But, OK, better like that!

For the sake of completeness, know that I first tried to add the background
fontification as a text property, but that made the other properties disappear
(annihilating the native fontification in fact). No a solution, or I did not
try the right way -- which is entirely possible, seen my poor knowledge on
this subject (I have to admit I succeeded by trials and errors).

Not that I can think of now. Sorry for not being of any help here.

Best regards,
