Dict formatting with 0.16.1

Dict formatting seems weird under 0.16.1. The value is added to a new line under the key, this seems somewhat silly, especially when the line length doesn't exceed `column_limit`. I don't see a tunable to disable this.

```
[style]
based_on_style = pep8
column_limit = 79
```

```
x = {
- 'ansible_host': '127.0.0.1',
- 'ansible_port': 2222,
- 'ansible_user': 'vagrant',
- 'ansible_private_key_file': '"/foo/bar"',
- 'connection': 'ssh',
+ 'ansible_host':

'ansible_ssh_extra_args': ('-o UserKnownHostsFile=/dev/null '
