    grohtml(1): Fix erroneous claim.
    
    * src/devices/grohtml/grohtml.1.man: Fix erroneous claim.  Images are
      not generated when "baseline rules" or "box rules" are encountered in
      the input.  These are troff special characters; the former is
      converted to an underscore and the latter to U+2502, "box drawings
      light vertical".  This remains true even if a series of them is drawn
      with the `\l` escape sequence.  (I also checked vertical line drawing
      with `\L`.  grohtml's handling of that provoked a rather wet
      eructation from my lower esophageal sphincter--the output is assuredly
      not correct.  But it's still not an image.)
    
    Play along at home!
