dont merge, example of issue.

currently in my shell
```
salt salt\* cloud -d
...
cloud.volume_detach:

    Detach volume from a server

    CLI Example:

        salt minionname cloud.volume_detach my-nova myblock                 server_name=myserver
```

if i change the code doc to:
```
    Detach volume from a server

    CLI Example:

    .. code-block:: bash

        salt minionname cloud.volume_detach my-nova myblock \\
                server_name=myserver

```

the doc looks correct:
...
cloud.volume_detach:

    Detach volume from a server

    CLI Example:

        salt minionname cloud.volume_detach my-nova myblock \
                server_name=myserver
```
