Yapf ~0.28.0~ 0.31.0 is still producing flake8 incompatible formatting.

Hi,

This directly relates to #694 which has been closed but is not fixed thus I open a new issue. I tried with 0.28.0 and I still have similar issues. Running `yapf -ri` on https://github.com/colour-science/colour/tree/46917f2b3ffefd7dd140384141302e3f87a69e99/colour/volume:

```bash
(colour-3.7) Kali:colour kelsolaar$ yapf -v
yapf 0.28.0
(colour-3.7) Kali:colour kelsolaar$ yapf -ri colour/volume/
(colour-3.7) Kali:colour kelsolaar$ flake8 colour
colour/volume/rgb.py:75:5: E131 continuation line unaligned for hanging indent
colour/volume/rgb.py:194:5: E131 continuation line unaligned for hanging indent
```

And here is the diff:

Another thing I notice is that some line returns are being removed which produces rather unelegant formatting, ~I will open a new issue for that~, see #744.
