Escape "\ m" в Ansible 2.9.4

Question

Я использую Ansible 2.9.4 и как-то при запуске следующего задания выдает ошибку escape:

sre_constants.error: bad escape \m at position 1

Любопытно, что это только сбой при итерации по \ m другие значения работают должным образом.

role / defaults / main.yml:

  motd_deleted_options:
  - "\\r"
  - "\\s"
  - "\\v"
  - "\\m"

role / tasks / main.yml:

- name: task - 1.8.1.1 Ensure message of the day is configured properly (Scored)
  lineinfile:
    path: /etc/motd
    regexp: "{{ item }}"
    state: absent
  loop: "{{ motd_deleted_options }}"

Задача состоит в том, чтобы делать то, что мне нужно, пока не достигнет "\ m", где в режиме отладки у меня есть:

[WARNING]: The loop variable 'item' is already in use. You should set the `loop_var` value in the `loop_control` option for the task to something else
to avoid variable collisions and unexpected behavior.
