[issue11548] Passing format= to unpack_archive fails

[Evan Dandrea]

New submission from Evan Dandrea <ev at ubuntu.com>:

Passing the format keyword parameter to shutil.unpack_archive triggers an exception:

Traceback (most recent call last):
  File "Lib/test/test_shutil.py", line 650, in test_unpack_archive
    unpack_archive(filename, tmpdir2, format=format)
  File "/home/evan/hg/cpython/Lib/shutil.py", line 741, in unpack_archive
    func(filename, extract_dir, **dict(format_info[1]))
TypeError: 'function' object is not iterable

This is due to that function incorrectly using the _UNPACK_FORMATS dictionary, which is fixed with the attached patch and test case.
