    [man]: Preserve user-selected font family.
    
    * tmac/an.tmac: When initializing, save the currently selected font
      family as `an*body-family` instead of forcing 'T' (Times, which is the
      formatter's default, even on nroff-mode devices that can't switch
      families).  This change makes the formatter's `-f` option work on
      man(7) documents again (important for Japanese man pages, but there is
      now once again nothing stopping you from viewing man pages in Palatino
      or Helvetica on the 'ps' and 'pdf' devices where these families are
      available).  It also reopens an avenue for rogue pages to affect the
      rendering of unrelated documents later in batch rendering, but there
      are many other, and worse, ways for rogue pages to do damage.  Problem
      introduced by me in commit e0e16d8e65, 15 March 2022.
    
    Fixes <https://savannah.gnu.org/bugs/?64130>.  Thanks to Deri James for
    the report.
