I defined an option like this:

```python
import morse
namespace.add_option(
'morsecode',
'',
'Turns morse code into real letters',
from_string_converter=morse.morse_load
)
```

and it works just fine but it's called more than once. Some times with a blank string. Sometimes with the default string and then with the actual input string.
