Completion doesn't work with referenced Object literal

Tern supports Object literal with this case : 

``` javascript
requirejs.config({
  // here Ctrl+Space show baseUrl
});
```

But if you declare the object literal in a var, it doesn't work : 

``` javascript
var config = {
  // PROBLEM : here Ctrl+Space doesn't show baseUrl
}
requirejs.config(config);
```
