The old line:
from path import path
produced pylint errors because of the baroque way that path.py defined
"path". We tried to get them to change how they defined it, but they
deleted the name instead: https://github.com/jaraco/path.py/issues/102
(Jason then changed his mind, but this is a better way to use path.py,
it avoids the pylint error at least.)
