Fix example usage for nested objects

Currently, the example shows an unnecessary object assigment
for nested parameters, e.g.

```
--instances object (multiple)

   Example:
     config=object; config.memory=float; config.cpu=float;
```

With this fix, the `config=object;` assigment will no be shown anymore:

```
--instances object (multiple)

   Example:
     config.memory=float; config.cpu=float;
```
