Code review comment for lp:~allenap/maas/docs-and-man-tidy

To sanity check things, I've used the following to compare the docs
generated in trunk to those generated in this branch:

  for file in docs/_build/html/*.html
  do
    echo === $file
    diff -u <(hxnormalize ../trunk/$file) <(hxnormalize $file)
  done

(hxnormalize comes from the html-xml-utils package.)
