replacing warnings.formatwarnings and to reverse replacement of
warnings.showwarnings when import is complete and when main function exits.
Add test_warning.py. Vinay Sajip provided capture_warnings function.

replacing redundant signature in input() docstring with one-line summary.
Original patch by Terrel Shumway.

There were no tests for the encoders module.  encode_base64 worked
because it is the default and so got tested implicitly elsewhere, and

fixed encode_noop, so this fix means that everythign in the encoders
module now works, hopefully correctly.  Also added an explicit test
for encode_base64.

time.strtime("%Y") returned "2345" when formatting year 12345.

string in longer than 2 gigabytes, and ssl.SSLContext.load_cert_chain() raises
a ValueError if the password is longer than 2 gigabytes. The ssl module does
not support partial write.

'Find in files' by replacing 'open with implicit close' by 'with open' in
