tracker issue 1671:

http://bugs.python.org/issue1671

In addition to updating the code for Py3k, this updates ccTLDs to their
10-Oct-2006 revision.

(Minor stylistic additions and whitespace normalization by Barry.)

by ISO 3166 as country codes, but the are reserved by IANA
nonetheless.  The commonly used uk ccTLD is part of this group, near
as I can tell.

Not sure this is better in all cases.

parse(): Fixed a bug in the output; the dict is referred to in the
code as `countries' not `country'.  Also added no-case-fold for the
string "U.S." since the Virgin Islands name no longer wraps those in
parentheses.

main(): Fixed the argument parsing to agree with the docstring, i.e.
--outputdict instead of --output.

In the module docstring:

- updated my email address
- we don't need to explain about Python 1.5 regexps <wink>

We also don't need to wrap the import of re with a try/except.

Other style fixes:

- untabification
- revert back to <> style everywhere (and consistently)

This patch replaces string module functions with string
methods in the Tools/world/world scripts.

It also updates two outdated URLs and the countrycodes
dictionary.

It fixes a bug where result of string.find() was checked
for truth instead of compared with -1.

It also replaces <> with != in two spots.

    there is "su" top level domain still maintained in ex-USSR.  at
    least "*.msk.su" zone (Moscow, USSR) is still in use.
