[issue10494] Demo/comparisons/regextest.py needs some usage information.

Not "+1" because Georg suggested that this demo be removed.  See

http://mail.python.org/pipermail/python-ideas/2010-October/008416.html

On the patch, I would define a "usage" variable near the top of the program instead of repeating the usage text in the comment.
