dateTime.iso8601 elements still unmarshal into xmlrpclib.DateTime objects

var == None and var != None
with
var is None and var is not None

and type(var) == int
with
instanceof(var, int)

...as recomended in PEP 8 [1].

* Use +=
* Replace loop logic with str.splitlines equivalent
* Don't use variable names that shadow tuple, list, and str
* Use dict.get instead of equivalent try/except
* Minor loop logic simplications

of a "in" or "not in" test.

Inspired by Skip's idea to recognize the throw-away nature of sequences
in this context and to transform their type to one with better performance.

Minor code clarification and simplification.

If we exit via the break here, we need to set ff_last_lineno or
FUTURE_POSSIBLE() will remain true.  The bug affected statements
containing a variety of expressions, but not all expressions.  It has
been present since Python 2.2.

a BOM.

for Python 2.4 caused a segfault when post_install_script was used.

The reason was that the file handle passed to PyRun_SimpleFile() was
created with MSVCRT.DLL, but Python 2.4 uses MSVCR71.DLL.

So, I replaced PyRun_SimpleFile() with PyRun_SimpleString().  The
segfault is gone, but the output of the postinstall script doesn't
show up, because still freopen() from MSVCRT is used.

Closes bug #1110998.  Thanks Matthew Bogosian.

Backported to 2.3 and 2.4.

Docs incorrectly stated that maxsplit=0 would cause unlimited splitting.

Saves space in the presence of code like: (None,)*10000
