    groff(7): Fix bug in `\?` escape rendering.
    
    * man/groff.7.man (ESC?): Fix bug in page-private macro: the question
      mark that ends this uniquely-syntaxed escape sequence was not shown
      with the mandatory escape character before it.  Problem dates back at
      least to commit 41b0e794, 19 February 2007, but possiby to f790bc7a9,
      6 January 2002.
