This essentially was due to the coding convention to put all ending
parentheses on the last line of the sexp, which most other programming
languages don't normally share.  But anyway.

Just want to say that a code snippet with unmatched ending parentheses
would confuse beginners a little.  However, if from a book writing point
of view that code snippets should be copied literally, it's probably
understandable (adding a small explanation for the extras would better
still, and I can update the patch accordingly.)

Wdyt?
