to Decimal, just as with all the other two-argument operations.

Thanks Mark Dickinson.

fully updated to the latests Decimal Specification (v1.66) and the
latests test cases (v2.56).

Thanks to Mark Dickinson for all his help during this process.

Fixes issue #1147.  Need to fix 2.5 to raise a proper warning if a string

Backport abc.py and isinstance/issubclass overloading to 2.6.

I had to backport test_typechecks.py myself, and make one small change
to abc.py to avoid duplicate work when x.__class__ and type(x) are the
same.

Make sure the type of the return value of re.sub(x, y, z) is the type
of y+x (i.e. unicode if either is unicode, str if they are both str)
even if there are no substitutions or if x==z (which triggered various
special cases in join_list()).

Could be backported to 2.5; no need to port to 3.0.

* Much expanded test suite:

  All protocols tested against all other protocols.
  All protocols tested with all certificate options.
  Tests for bad key and bad cert.
  Test of STARTTLS functionality.
  Test of RAND_* functions.

* Fixes for threading/malloc bug.

* Issue 1065 fixed:

  sslsocket class renamed to SSLSocket.
  sslerror class renamed to SSLError.
  Function "wrap_socket" now used to wrap an existing socket.

* Issue 1583946 finally fixed:

  Support for subjectAltName added.
  Subject name now returned as proper DN list of RDNs.

* SSLError exported from socket as "sslerror".

* RAND_* functions properly exported from ssl.py.

* Documentation improved:

  Example of how to create a self-signed certificate.
  Better indexing.

Closes issue #1096.

I chose IOError rather than EnvironmentError as the base class since
socket objects are often used as transparent duck typed file objects
in code already prepared to deal with IOError exceptions.

also a minor fix:

 urllib2 - fix a couple places where IOError was raised rather than URLError.
           for better or worse, URLError already inherits from IOError so
           this won't break any existing code.

 test_urllib2net - replace bad ftp urls.
