Code to reproduce

from sys import path as sys_path

# Nothing here, just need to room to move add lines

Reported error
F401 — 'sys.path as sys_path' imported but unused at line 5 col 1 in test.py

Expected error
F401 — 'sys.path as sys_path' imported but unused at line 1 col 17 in test.py
With the whole of path as sys_path underlined.

Just as an FYI, as part of the ES2017 re-write I'm working on I'm investigating this. I'm still not sure whether I want to keep the mass of code that is the "position fixing" and get it working properly, or just go back to the incorrect results from flake8...

Fixed in #255. Although the specs don't show it, it does work with that syntax, it's just that the hacking module forces an older version of flake8 that only marks the alias.
