backported to 23-maint

Sure looks like it to me! <wink>

When I run the leak2.py script I posted to python-dev, I only see
three reference leaks in all of test_descr.  When I run
test_descr.test_main, I still see 46 leaks.  This clearly demands
posting a yelp to python-dev :-)

This certainly should be applied to release23-maint, and in all
likelyhood release22-maint as well.

which can now take zero arguments.

* Simplify the pure python examples
* Add a quantify() example

Include a test case that failed for one of my efforts to repair this.

Backporting to Python 2.3 branch.

Will also check in on the 2.3 branch.

    LaTeX2HTML feels free to remove a surrounding element that
    contains no other content.  Since such an element is typically a
    named anchor used for hyperlinking, they should not be removed.
    Unfortunatley, making sure these marks are non-empty is the most
    direct way of avoiding this behavior.

Thanks to Dave Kuhlman for tracking this down; this was some excellent
detective work!

Also remove now unnecessary property attributes for thread safety
(no longer have lazy attributes) and code simplicity reasons.

Timezone storage has been reworked to be simpler and more flexible.  All values
in LocaleTime instances are lower-cased.  This is all done to simplify the
module.

The module now assumes nothing beyond the strptime function will be exposed for
general use beyond providing functionality for strptime.
