I received a PGP message, hwere gnus buttons were added in the middle of
    PGP block:

        noRr110XVahfo/3MaLL2PGlJ/h8rOdZkJCPCQ1OO8BKcXg3NQWTb+RpqSbSRnbEq
        [...]
        win0apLYccO+tqhhzK3CIiDbgBGfQLNU9ju+nMOOm1VUfF2A/phMoQg6ucYrXFxk

    But I was suprised when I entered edit mode that the buttons were
    still there. I would have expected that gnus-original-article-buffer
    were offered for me to edit

    This patch copies gnus-original-article-buffer to the edit
    buffer so that used really edits the original content.
