2268	generic views should call Manipulator.prepare()	mir@…	Jacob	"Within the FormField framework, Manipulators and FormFields have
a method `prepare()`. Its docstring says:

{{{
    def prepare(self, new_data):
        """"""
        Makes any necessary preparations to new_data, in place, before data has
        been validated.
        """"""
}}}

It would also be a nice place for this, but ... in reality, it never gets called.

If generic views called it before get_validation_errors (as the
docstring of prepare suggests), it would be a good place to add
logic for readonly fields (to replace them from original_object)

Furthermore, CheckboxSelectMultipleField overwrites prepare,
although it never gets called. I haven't used it, so can't say if
it's buggy.

Or am I missing something?
