    Added errors argument to TarFile class that allows the user to
    specify an error handling scheme for character conversion. Additional
    scheme "utf-8" in read mode. Unicode input filenames are now
    supported by design. The values of the pax_headers dictionary are now
    limited to unicode objects.

    Fixed: The prefix field is no longer used in PAX_FORMAT (in
    conformance with POSIX).
    Fixed: In read mode use a possible pax header size field.
    Fixed: Strip trailing slashes from pax header name values.
    Fixed: Give values in user-specified pax_headers precedence when
    writing.

    Added unicode tests. Added pax/regtype4 member to testtar.tar all
    possible number fields in a pax header.

    Added two chapters to the documentation about the different formats
    tarfile.py supports and how unicode issues are handled.

  Fix a fairly long-standing bug in the check for assignment to None (and other
  keywords, these days).  In 2.5, you could write foo(None=1) without getting
  a SyntaxError (although foo()'s definition would have to use **kwds to avoid
  getting a runtime error complaining about an unknown keyword of course).

  This ought to be backported to 2.5.2 or at least 2.6.
