ImageField/FileField behaviour on ModelForms

When an ImageField is left blank on a ModelForm, and the underlying instance already has an image, the image remains. It isn't overwritten with None (removed).
This behaviour is good design :-) But it isn't documented, it isn't consistent with the behaviour of the other fields, and it doesn't provide a way of removing an image (I recall this was a problem with admin, not sure if it still is).
I suggest we add a note to the ModelForms doc to let people know that blank ImageFields won't remove existing images. Also, we might want to consider automatically adding an extra non-required BooleanField to the ModelForm, maybe remove_FIELDNAME.
