documentation problem regarding user groups

[Sunil K Chopra]

In the latest documentation examples, the first example has an apparent error on line 14.

http://cloudinit.readthedocs.io/en/latest/topics/examples.html

```
# Add users to the system. Users are added after groups are added.
users:
  - default
  - name: foobar
    gecos: Foo B. Bar
    primary-group: foobar
    groups: users
```

It shows that a string is an acceptable value for the `groups` key. On line 23, it shows another string with comma-separated values. Both of these values cause errors. The `groups` key requires an array, even if there is only one value. This is implied at line 109, but not explicitly stated.

Please fix?

thanks!

Sunil

Hi,
In bug 1562918 cloud-init code was fixed so that the documentation was correct.
See the commit message for examples.

If you find otherwise, please re-open.
