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.
