Comment 0 for bug 1665773

example config in documentation is:
```
  chpasswd:
    list:
      - user1:password1
      - user2:Random
      - user3:password3
      - user4:R
```
but cc_set_passwords fails with config above (LP#1665694)

Actually testcase for the module uses multiline string https://git.launchpad.net/cloud-init/tree/tests/cloud_tests/configs/modules/set_password_list.yaml#n21
and therefore documentation should contain:
```
  chpasswd:
    list: |
      tom:mypassword123!
      dick:R
      harry:Random
