Whitespace validates in any field that is required

How to reproduce:
Create a form with a CharField that has required=True .
Put whitespace into the field ( for example 4 spaces ).
Submit the form. It will validate as is_valid().
The problem lies in fields.py at line 111 ( django trunk ):
def clean(self, value): """ Validates the given value and returns its "cleaned" value as an appropriate Python object. Raises ValidationError for any errors. """ if self.required and value in EMPTY_VALUES: raise ValidationError(self.error_messages['required']) return value
At line 46 is the following:
# These values, if given to to_python(), will trigger the self.required check. EMPTY_VALUES = (None, '')
Problem is that any amount of whitespace will get through this check. I don't know how you guys think about this ( I mean, whitespace is data ;-) ), but filling in whitespace has pretty much the same effect as filling in nothing.
if self.required and value.rstrip() in EMPTY_VALUES:
I know I should do this with a patch etc. but I don't know how to do this. I hope this is sufficient.
Thanks in advance,
