Docs: 'author-detail' vs 'author_update'

[Thomas Güttler]

Please use one form to refer to the update-view of
a model.

Here are two: 'author-detail' vs 'author_update'

    def get_absolute_url(self):
        return reverse('author-detail', kwargs={'pk': self.pk})

from ​https://docs.djangoproject.com/en/1.8/topics/class-based-views/generic-editing/#model-forms

some lines below the above link:

    url(r'author/(?P<pk>[0-9]+)/$', AuthorUpdate.as_view(), name='author_update'),

But first: The django core developers should decide which pattern should be used in the docs:

foo-detail or foo_update.

When the decision was made, then all examples in the docs should use this pattern.
