Comment out ch5-impossible-add book notes

FTR, there's also an additional problem in the book text (or the naming of the file in the repo). The book says:
but the actual file is called:
Ie, one has the suffix "-addition", and one has the suffix "-add"; the meaning is similar, but anyone cut'n'pasting filenames to look for will be confused. (It's probably easier to rename the file in the repo to match the book text. ETA: The second half of page 141, of the PDF version, uses the name matching the repo; so maybe it's just the "look in" reference that introduces it which has the wrong name.)
Anyway I can confirm properly commenting out the book reference markers does allow the example to compile.
