Objects with primary keys containing newlines do not get links to being edited in the admin list view

Description (last modified by )
The admin list view of an object lists each object and does a
reverse('admin:%s_%s_change' % (self.opts.app_label, self.opts.model_name), args=(quote(pk),), current_app=self.model_admin.admin_site.name)
to assign a change url for each one, skipping the link if the reverse fails. The 'quote' function there escapes a whole bunch of characters so as not to confuse the url pattern matcher but it forgets to escape newline.
Therefore, a model like this:
class Name(models.Model): name = models.TextField(primary_key=True)
with:
n = Name('John') n.save() o = Name('Have a \n newline') o.save()
will list a link for John, but no link for 'Have a newline'
(The bug actually is triggered in quite a few other places in admin but the list view is the easiest one to see. I've attached some screenshots that I prepared earlier)
Change is a 2-character change to quote \n as well (attached)
