Remove unnecessary "," from Pylint version regex
See PHI1238. This "," in the regex can only make the lint binding fail if there is no "," in the version output string. In modern versions of Pylint, there is (apparently) no comma in the version string. Remove it.
$ pip install pylint Traceback (most recent call last): File "/Users/epriestley/Library/Python/2.7/bin/pip", line 6, in <module> from pip._internal import main ImportError: No module named pip._internal
