pydocstyle fails on "raise X from Y"

[Nurdok]

The reason is that the "from" keyword triggers a "from X import Y" parsing, which fails.

Should this be on the 1.1.0 milestone? (https://github.com/PyCQA/pydocstyle/milestone/4)

Any progress / insights on this one?

This is solved in #200 and it will definitely be in the next release - still working on the PR though. Hopefully it will be done this week.
