Bastien Guerry 6e534f9c61 Manually revert back to commit e85080.
This fixes a wrong merge that should not have happened:
commit 7e903a merges the master branch into the maint branch,
while we really want to keep the maint branch a bugfix-only
branch.

This commit reverts back the maint branch to its state before
merging the master branch.  From there, we will fix remaining
problems with the maint branch (e.g. copyright issues) then
release this maint branch as Org-mode 7.8.05.

;;; Commentary:
;;
;; This package generalizes the #+begin_foo and #+end_foo tokens.
;; To use, put the following in your init file:
;;
;; (require 'org-special-blocks)
;; The tokens #+begin_center, #+begin_verse, etc. existed previously.
;; This package generalizes them (at least for the LaTeX and html
;; exporters). When a #+begin_foo token is encountered by the LaTeX
;; exporter, it is expanded into \begin{foo}. The text inside the
;; environment is not protected, as text inside environments generally
;; is. When #+begin_foo is encountered by the html exporter, a div
;; with class foo is inserted into the HTML file. It is up to the
;; user to add this class to his or her stylesheet if this div is to
;; mean anything.
