case of objects with equal types which support tp_compare. Give
type objects a tp_compare function.
Also add c<0 tests before a few PyErr_Occurred tests.

added test script and expected output file as well
this closes patch 103297.
__all__ attributes will be added to other modules without first submitting
a patch, just adding the necessary line to the test script to verify
more-or-less correct implementation.

                 as a parameter; this was the only use of the base
                 constructor or surgical alteration of another object's
                 data attribute.

This change simplifies the constructor requirements for subclasses.

This relates to SourceForge bug #115928.

rfc822 (Addresslist) modules. Also a preliminary testcase for augmented
assignment, which should actually be merged with the test_class testcase I
added last week.

comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

add test cases for non-UserList class, tuple, & string

    1. Comments at the beginning of the module, before
       functions, and before classes have been turned
       into docstrings.

    2. Tabs are normalized to four spaces.

Also, removed the "remove" function from dircmp.py, which reimplements
list.remove() (it must have been very old).

Reformatted with 4-space indent.

  reduce)
* ftplib.py: added default callback for retrlines; added dir() method
* ftplib.py: don't return self in self.connect(); added hack so that if
  'CDUP' is not understood, 'CWD ..' is tried.
* ftplib.py: second method called init() should have been called
  connect(); if __init__ sees more than one argument, it will also try to
  login().
