Inspired by Django's urlize function.
Positive examples:
>>> import markdown
>>> md = markdown.Markdown(extensions=['urlize'])
>>> md.convert('http://example.com/')
u'<p><a href="http://example.com/">http://example.com/</a></p>'
>>> md.convert('go to http://example.com')
u'<p>go to <a href="http://example.com">http://example.com</a></p>'
>>> md.convert('example.com')
u'<p><a href="http://example.com">example.com</a></p>'
>>> md.convert('example.net')
u'<p><a href="http://example.net">example.net</a></p>'
>>> md.convert('www.example.us')
u'<p><a href="http://www.example.us">www.example.us</a></p>'
>>> md.convert('(www.example.us/path/?name=val)')
u'<p>(<a href="http://www.example.us/path/?name=val">www.example.us/path/?name=val</a>)</p>'
>>> md.convert('go to <http://example.com> now!')
