[issue7712] Add a context manager to change cwd in test.test_support

[Florent Xicluna]

Florent Xicluna <la...@yahoo.fr> added the comment:

A patch which provides a context manager and a decorator.
(with ideas from Ezio and Antoine)

Sample usages:

with temp_cwd() as cwd:
  assert cwd == os.getcwd()


@writablecwd
def test_zipfile():
  # do something useful
  print os.path.abspath('.')
