Bug report

Bug description:

>>> from email.policy import Policy
>>> Policy.mangle_from_
False
>>> print(Policy.__doc__)
...
    mangle_from_        -- a flag that, when True escapes From_ lines in the
                           body of the message by putting a `>' in front of
                           them. This is used when the message is being
                           serialized by a generator. Default: True.

This attribute was added in fdb23c2 and was always False by default, as far as I can see.

The docs also correctly say that it defaults to False. I don't know why the class docstring says otherwise.

I think this can be closed now, right? Not sure why this didn't auto-close when the PR was merged.
