  Issue 2778.  Document the temporary frozenset swap in __contains__(), remove(), and discard().

  Make test.test_support.catch_warning() take an argument specifying if any
  triggered warnings should be captured. This allows the context manager to be
  used to just prevent the internal state of the 'warnings' framework and thus
  allow triggered warnings to be displayed.

  r62892 | brett.cannon | 2008-05-08 15:20:24 -0500 (Thu, 08 May 2008) | 4 lines

  Fix a bug introduced by the addition of the 'record' argument to
  test.test_support.catch_warning() where showwarning() was not being set
  properly.

  Fix sys.flags to properly expose bytes_warning.

  Closes issue #2790.
