commit f5743282a313bdfc85b404985d1659d2e9e19b99

    [mdoc]: Drop dead code.
    
    The register `doc-volume-operating-system-ateol`, introduced in groff
    1.18 {July 2002}, was being tested but never set to a nonzero value.  In
    fact, it seems never to have been.
    
    * tmac/mdoc/doc-common: Get rid of it...
    
      (Dt): ...and the dependent block.
    
    This commit does not update indentation, because other, long-standing,
    misleading indentation is adjacent, so I will fix those together.
