    Revert "[mdoc]: Reserve registers used by groff_man(7)."
    
    This reverts commit 8c25d2a1ed2f0046b355b640ed09626c01ac3b7d.
    
    The method I attempted to prevent future squatting on the page rendering
    option name space did not work, and caused problems with some batch man
    page rendering scenarios.
    
    Fixes <https://savannah.gnu.org/bugs/index.php?60589>.
