    groff(7): Fix errors and an oversight.
    
    * Only one extremum is computed by an operator.
    * Favor imperative mood where this achieves brevity.
    * Set an ellipsis in a table heading in the correct face (bold, not
      roman).
    * Correct mistaken metasyntactic variable names.
    * Drop duplicated phrase.
    * Cross reference `systat` register from `sy` request description.
