    Strip out the current working directory from sys.path.
    Having the working directory in `sys.path` means that `pylint` might
    inadvertently import user code from modules having the same name as
    stdlib or pylint's own modules.
    CPython issue: https://bugs.python.org/issue33053

    - Remove the first entry. This will always be either "" or the working directory
    - Remove the working directory from the second and third entries. This can
      occur if PYTHONPATH includes a ":" at the beginning or the end.
      https://github.com/PyCQA/pylint/issues/3636
    - Don't remove the working directory from the rest. It will be included
      if pylint is installed in an editable configuration (as the last item).
