    [mm]: Make reference list more flexible.
    
    Make new `LB`-based approach to reference page work both with documents
    that use refer(1) to collect references and those that use only mm(7)'s
    own facilities.
    
    * contrib/mm/m.tmac (ref@start-print): Change `LB` list "type" argument
      from 1 (enumerated) to 0 (string-based).  This is because the
      reference marks are self-enumerating.  However, this loses their
      trailing dots, so update `LI` call to add them back in.
    
    * contrib/mm/refer-mm.tmac (ref*biblio-item-sfx): Define as empty,
      overriding "refer.tmac"'s default.  As shown above, our own
      infrastructure supplies the dot suffix now.
