[Python-projects] VariablesChecker._vars

[skip at pobox.com]

I noticed in pylint's VariablesChecker.visit_function an empty dict is
appended to its _vars attribute:

    self._vars.append({})

but in its leave_function the first element is popped:

    self._vars.pop(0)

It seems like like it should just be

    self._vars.pop()

Fortunately it seems that _vars isn't used.
