    man/groff.7.man: Update request short reference.
    
    * Add more cross references to related requests as registers.
    * Recast descriptions of Boolean-valued registers for consistency.
    * Clarify behavior of `.z` register when in top-level diversion, a term
      that once was not defined in this man page but now is.
