New submission from Nick Coghlan <ncogh...@gmail.com>:
A bug report for the incompatibility I was trying to explain on the checkins
list. The test_support module is the only part of the regression test suite
that is officially documented, so we can't go changing behaviour that is
visible to third parties at will.

>>> from test.test_support import check_warnings
>>> with check_warnings():
... pass

Third party test suites may want to use check_warnings() for both 2.6 and 2.7
and this change makes it unnecessarily difficult for them to do so.
Fixing this should just be a matter of flipping the default value of the new
"quiet" parameter to True and updating the tests and documentation accordingly.
