import pynvim 'disables' logging globally

[jeff-dh]

import logging
import pynvim

logging.error('this will not show up as long as pynvim is imported')

The reason are these lines in pynvim/__init__.py:149ff:

# Required for python 2.6
class NullHandler(logging.Handler):
    def emit(self, record):
        pass

if not logging.root.handlers:
    logging.root.addHandler(NullHandler())
