Snapshot changes to generated ch7 that SHOULDN'T be sent to nostarch

This snapshot contains line wrapping problems, irrelevant comments,
extraneous output lines, and differences we're going to allow between
the online and print version.

The intention is to make this a baseline commit for chapter 7 that we
can diff against to find changes to consider sending to nostarch as tiny
tweaks.

Also removing the word doc verison of this chapter as generating this
file from it will produce different, irrelevant changes, and this doc
should no longer be used for any purpose.
