Fixed #25369 -- Corrected syndication's get_object() example.

Here's the code for these beat-specific feeds::

    from django.contrib.syndication.views import Feed

    from django.shortcuts import get_object_or_404

    class BeatFeed(Feed):

        description_template = 'feeds/beat_description.html'

        def get_object(self, request, beat_id):

            return get_object_or_404(Beat, pk=beat_id)

            return Beat.objects.get(pk=beat_id)

        def title(self, obj):

            return "Police beat central: Crimes for beat %s" % obj.beat
