[issue7847] Remove 'python -U' or document it

[Barry A. Warsaw]

New submission from Barry A. Warsaw <barry at python.org>:

Python 2.x supports a -U flag which has the effect largely the same as 'from __future__ import unicode_literals'.  However -U is undocumented anywhere except import.c.  We should either remove -U support from Python 2.7 or document it (and indicate in that documentation that the future import is preferred).
