commit 3befb0c6aeeb7edb06af8e296d13ec9989272471
Author: G. Branden Robinson <g.branden.robinson@gmail.com>

    pic(1): Fix style nits.
    
    * Use independent clause in imperative mood when characterizing options.
    * Add comma after phrase used as restrictive modifier.
    * End sentence with period, not colon.  The word "following" does not
      excuse you from the rules of English grammar (in formal writing).
    * Say "GNU pic" explicitly when distinguishing this implementation's
      behavior from others.
    
    Also fix markup nit: migrate from `LP` to `P` macro.
