29316	TypeError when defining `strip` on a CharField	Daniel Finch	nobody	"In Django 1.9 the [https://docs.djangoproject.com/en/1.9/ref/forms/fields/#django.forms.CharField.strip `strip` argument] was added #4960, but if you actually specify it on a CharField you get a TypeError.  This means that you cannot disable it by setting `strip=False` - you can't even set `strip=True` if you wanted to for whatever reason.

I've created a minimal reproduction of the problem, it's available [https://github.com/danielsamuels/django-strip-false-test on Github].  The traceback is as follows:

The error seems to be as simple as the `Field` class missing the `strip` attribute in it's `__init__` method."	Bug	closed	Database layer (models, ORM)	2.0	Normal	invalid		Daniel Finch	Unreviewed	0	0	0	0	0	0
