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.
