This change is mostly autogenerated with:

    $ python -m autoflake --in-place --recursive examples templates transformers utils hubconf.py setup.py

I made minor changes in the generated diff.

Ignore warnings related to Python 2, because it's going away soon.

Fixes flake8 warning W291 (x224).

This is the result of:

    $ isort --recursive examples templates transformers utils hubconf.py setup.py

This is the result of:

    $ black --line-length 119 examples templates transformers utils hubconf.py setup.py

There's a lot of fairly long lines in the project. As a consequence, I'm
picking the longest widely accepted line length, 119 characters.

This is also Thomas' preference, because it allows for explicit variable
names, to make the code easier to understand.

* Small clarification

Matches line 431 to line 435 for additional clarity and consistency.

* Fixed minor typo

The letter "s" was previously omitted from the word "docstrings".

Removed duplicate XLMConfig, XLMForQuestionAnswering and XLMTokenizer from import statement of run_squad.py script

Updated documentation due to typo
