+Subject: The GNU Awk User's Guide, Section 13.3.11
+From: "Chris Johansen" <address@hidden>
+Message-ID: <address@hidden>
+Arnold, you don't know me, but we have a tenuous connection.  My wife is  
+Barbara A. Field, FAIA, GIT '65 (B. Arch.).
+I have had a couple of paper copies of "Effective Awk Programming" for  
+years, and now I'm going through a Kindle version of "The GNU Awk User's  
+Guide" again.  When I got to section 13.3.11, I reformatted and lightly  
+commented Davide Brin's signature script to understand its workings.
+It occurs to me that this might have pedagogical value as an example  
+(although imperfect) of the value of whitespace and comments, and a  
+starting point for that discussion.  It certainly helped _me_ understand  
+what's going on.  You are welcome to it, as-is or modified (subject to  
+Davide's constraints, of course, which I think I have met).
+If I were to include it in a future edition, I would put it at some  
+distance from section 13.3.11, say, as a note or an appendix, so as not to  
+be a "spoiler" to the puzzle.
+Best regards,
+Chris Johansen {johansen at main dot nc dot us}

+certainty through the space-time continuum.
