urlize doesn't handle extra punctuation after the link properly

[Lee Semel]

In the code below, the first call to urlize() works as expected, excluding the period from the url. I'd have expected the other examples to also exclude the punctuation from the link, but it always pulls in all of the punctuation save for the last character.

>>> from django.utils.html import urlize
>>> urlize('This is a test http://testing.com/example.')
u'This is a test <a href="http://testing.com/example">http://testing.com/example</a>.'
>>> urlize('This is a test http://testing.com/example..')
u'This is a test <a href="http://testing.com/example.">http://testing.com/example.</a>.'
>>> urlize('This is a test http://testing.com/example!!')
u'This is a test <a href="http://testing.com/example!">http://testing.com/example!</a>!'
>>> urlize('This is a test http://testing.com/example!!!')
u'This is a test <a href="http://testing.com/example!!">http://testing.com/example!!</a>!'
