> 1. Create bug.el:
> (require 'org-faces)
> (set-face-underline 'org-block-end-line t)
> (setq org-fontify-whole-block-delimiter-line t)
> 
> 2. Create bug.org:
> #+begin_src
> #+end_src
> 
> asd
> 
> 3. Move point to the end of #+end_src line:
> #+end_src<point>
> 
> 4. M-x open-lien
> 
> 5. Observe underline face being applied to the empty line _after_
> #+end_src.
