    [tmac]: Revise "fallback" character definitions.
    
    ...in several respects for Unicode characters from General Punctuation
    block.
    
    * tmac/fallbacks.tmac: Comment out fallbacks for U+200B, U+2010, U+2011,
      and U+201[89CD], due to ineffectuality or apparent groff bugs.
      Redefine U+2012 fallback to include hair space (\^) around synthetic
      figure dash.  Redefine U+2016 to use `\[ba]` special characters
      instead of ordinary `|` characters to dodge possible character
      translations by user.
    
    Fixes part of <https://savannah.gnu.org/bugs/?63354>.  Thanks to Dave
    Kemper for the (multifarious) discussion.
