commit 895bf9897e8564eb514b1fd6b14ee1670bfe611f

    nroff(1): Fix style nits.
    
    * Place multi-word parentheticals on their own input lines.
    * Say "AT&T" instead of "traditional Unix".
    * Be more pendatically precise; we pattern-match the _contents_ of
      environment variables for a character encoding.
    * Add non-printing break point before "." in file name.
    * Comment un-@g@-prefixed command name instances so we know they've been
      checked for contextual correctness.
