- When adding a view for a route which did not yet exist ("did not yet

  exist" meaning, temporally, a view was added with a route name for a
  route which had not yet been added via add_route), the value of the
  ``custom_predicate`` argument to ``add_view`` was lost.  Symptom:
  wrong view matches when using URL dispatch and custom view
  predicates together.
