    grodvi(1): Fix page-local .FT macro usage.
    
    ...and comment it.
    
    * src/devices/grodvi/grodvi.1.man: Comment .FT.  We look at most
      page-local macros with a jaundiced eye, but like its counterparts in
      gropdf(1) and grops(1), this one pays its freight (also see
      b21c2aed716bff4f94dcadd43e878ec3063a132c, 16 August 2020).
    
      (Usage): In the case of the CW and CWI fonts, the lines were
      incorrectly ordered so these fonts did not appear in the rendered
      document.  (Note: you have to generate the page with -Tdvi and then
      use dvips or dvipdf for _any_ of the font switches intended by .FT.)
      Problem dates back to 16f754849f33318320f0d06c4d303b1b1df524f4, 26
      February 2002).
