    groff_mm(7): Fix error; AU argument is mandatory.
    
    Problem dates back to commit af2d6f8e589f9fc58b98fafaad36f90302ca4b62,
    groff 1.14 (1999-12-26).
    
    groff mm in 1.22.4 and earlier did not complain if `AU` was given no
    arguments, but it does now.  See <https://savannah.gnu.org/bugs/?60926>.
    
    AT&T/DWB mm(7) documents a first argument as mandatory (several further
    arguments are optional).  See p. 23 of "MM - Memorandum Macros" by D.
    Smith, Mashey, Priser, and N. Smith (June 1980 revision).
