The syntax for disabling multiple warnings in one line is too strict

[Mikhail Dubov]

As of now, the # noqa: ... statement disables only the first warning when the corresponding codes are separated by ', ' (with a space), e.g. the following will only disable Q440:

# noqa: Q440, Q447, Q448, Q449

-- which might be confusing if you don't know that spaces are not allowed (they probably should be). The following still disables all the warnings:

# noqa: Q440,Q447,Q448,Q449

[Phil Jones]

This is something that is fixed in flake8, recently, so presumably on that release you can use spaces.
