When creating a form from model, the most effective way for modification
of several fields at once is `formfield_callback`. While it is documented
argument of `modelform_factory` which is used for dynamically created
forms, the attribute `formfield_callback` on statically defined
`ModelForm` remains undocumented. There is growing evidence, that despite
it isn't documented it is generally used or required, see #17924,

widget-for-all-django-date-fields-in-a-modelform,
http://stackoverflow.com/questions/7342925/django-problem-inheriting-
formfield-callback-in-modelforms
I don't require any change of functionality, I just want the following two
methods to create a model form to be equal:
{{{
#!python
# This works, but it's hard to read on a module level.
MyModelForm = modelform_factory(MyModel, formfield_callback=my_callback)
# This does the same thing, but it's not documented.
class MyModelForm(forms.ModelForm):
formfield_callback = my_callback
class Meta:
model = MyModel
}}}
