SimpleFormValidator obscures my docstrings (and doctests!)

I wrote some doctests on a validator, then discovered that decorating
with SimpleFormValidator means that those doctests are on the inner
func attribute, not the outer object, so as far as I can tell, I can
run those doctests.

Trivial example:

>>> @SimpleFormValidator.decorate()
def f(value_dict, state, validator):
    """
    Add a new key 'f' pointing to 99 to value_dict.
    """
    value_dict['f'] = 99
...
>>> f().to_python({}, None)
{'f': 99}

Here's the problem: the docstring on the decorated f is really the
SimpleFormValidator's docstring:

>>> f.__doc__ == SimpleFormValidator.__doc__
True

Luckilly, the originally docstring is still alive, just hidden inside:

>>> print f.func.__doc__

    Add a new key 'f' pointing to 99 to value_dict.

I'm trying to write some doctests for my validator f, but my test
runner (nose) doesn't run the doctests.

Any ideas about a solution?
