Nested @option is not working correctly

Example source:

```
@property {String|{}} connection.url url
@parent can-connect.options

@option {String}

As a string.

@option {{getListData: String, getInstanceData: String}}

As an object.

@option {String} getListData abc

@option {String} getInstanceData def
```

No file or test is named. Start by reproducing the example source and inspect how nested @option annotations are parsed; done means the string and object forms, including getListData and getInstanceData, are documented correctly.
