    [docs]: Regularize discussion of GROFF_TMAC_PATH.
    
    * doc/groff.texi (Environment): Recast to simplify and describe portably
      (the path separator is platform-specific).  Add cross reference to
      formatter man page.
    
    * src/roff/groff/groff.1.man (Environment): Recast to simplify.  Set man
      page cross reference in italics, not bold.
