[1.3.X] Fixed #17706 - Improved short description example in Tutorial 2; thanks xbito and claudep.

underscores replaced with spaces). But you can change that by giving that

method (in ``models.py``) a ``short_description`` attribute::

    class Poll(models.Model):

        # ...

        def was_published_today(self):

            return self.pub_date.date() == datetime.date.today()

        was_published_today.short_description = 'Published today?'
