Right. Let me point out that this is the case if you want to have a 
flexible part with one flexible widget already created. Otherwise (void 
schema, templates with '?' for fields only), the consistentency would 
be better.

The first field used to be labeled simply 'file'.  This changed 
somewhere between 3.3.5 and 3.3.8. Before that, the transition between 
flexible and flexible predefined fields/widgets was smoothier. I forgot 
the reason of the change, just remember that the explanation was 
convincing when I asked for it.

Thanks for the patch.
