Patch # 1140 (my code, approved by Effbot).
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.

Patch # 1026 by Benjamin Aranguren (with Alex Martelli):
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.

Merged the decimal-branch (revisions 54886 to 58140). Decimal is now

Add support for asyncore server-side SSL support. This requires
adding the 'makefile' method to ssl.SSLSocket, and importing the
requisite fakefile class from socket.py, and making the appropriate
changes to it to make it use the SSL connection.
Added sample HTTPS server to test_ssl.py, and test that uses it.
Change SSL tests to use https://svn.python.org/, instead of
www.sf.net and pop.gmail.com.
Added utility function to ssl module, get_server_certificate,
to wrap up the several things to be done to pull a certificate
from a remote server.

Sync-up named tuples with the latest version of the ASPN recipe.
