title: extending urlize in django
body: <p>the urlize function from django.utils.html converts urls to clickable links. My problem is that I want to append a target="_blank" into the "&lt; href..>", so that I open this link in a new tab. Is there any way that I can extend the urlize function to receive an extra argument? or should I make a custom filter using regexes to do this stuff? Is this efficient?</p>
