[O] Background color reset for links and DONE headlines

[Sebastien Vauban]

Hello,

As you can see on http://screencast.com/t/xdVGDQrbB, faces for DONE headlines
or hyperlinks seem to reset the background color of the elements they're
applied onto, even if they don't have any background color specified:

--8<---------------cut here---------------start------------->8---
`(org-link ((,class (:underline t :foreground "#006DAF"))))
`(org-headline-done ((,class (:height 1.0 :weight bold :strike-through 
"#BEBEBE" :foreground "#C5C5C5"))))
--8<---------------cut here---------------end--------------->8---

I see that the font is set in defun `org-set-font-lock-defaults' (L6039--6045
of `org.el'), but it seems to me we can only give one face through that
mechanism. Am I right?  Is this a limitation we can work around?

Best regards,
  Seb
