    [mm]: Fix another cover sheet nit.
    
    * contrib/mm/mm/ms.cov (COVEND): Fix thinko; test for existence of
      `cov*abs-arg` register with `r` conditional operator, not `d`.
      Also fix style nit; wrap excessively long line.
    * contrib/mm/groff_mm.7.man (Macros) <AS>: Describe operation more
      accurately.
