Steps to reproduce

Call pylint from a python script as:
(pylint_stdout, pylint_stderr) = lint.py_run(command_options = "%s -E --msg-template={path} {msg} my_module.py", return_std=True)
and print the output of pylint_stdout.readlines()

Current behavior

When printed, pylint_stdout is not formatted as defined in command_options (see above), but instead, the message is shown as defined in pylint/eplyint.py (line 90-92):

cmd = [sys.executable, "-c", run_cmd] + options + [
'--msg-template', '{path}:{line}: {category} ({msg_id}, {symbol}, {obj}) {msg}',
'-r', 'n', child_path]

Expected behavior

The output when printing pylint_stdout.readlines() should be:

PATH MSG

But you get, instead:

PATH:188: error (E1101, no-member, OBJECT) MESSAGE

pylint --version output
