Comment 3 for bug 1669305

Before this bug is closed, please think about if this also affects newton. My comment from the change:

"Mitaka is not affected. Newton is affected, but contains a lot more errors when running 'tox -e docs' How to handle this?"

Here is the summary of tox -e docs in Newton:
Total files scanned = 40
Total files ignored = 0
Total accumulated errors = 139
Detailed error counts:
    - doc8.checks.CheckCarriageReturn = 0
    - doc8.checks.CheckIndentationNoTab = 0
    - doc8.checks.CheckMaxLineLength = 126
    - doc8.checks.CheckNewlineEndOfFile = 1
    - doc8.checks.CheckTrailingWhitespace = 1
    - doc8.checks.CheckValidity = 11
