[issue1474680] pickling files works with protocol=2.

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Pickling a file is tricky. You can't just pickle the construction
parameters, you also need to save (and restore) the whole buffering
state. I'm not sure a half-working pickle solution would make a good
service to the user.
