    [mm]: Tweak nroff `Sm`, `Tm` string definitions.
    
    * contrib/mm/m.tmac (Sm, Tm): Tweak string definitions to use half-line
      motions in nroff mode when the font lacks a dedicated glyph.  At
      present no nroff device supports half-line motions, but this prepares
      us if we ever do, and DWB 3.3 mm does specify this behavior on page
      A-2 of its manual.
