Deep recurrence displays invalid path

[rettier]

In my project i had an urlpattern which included another urlpattern. The current code does resolve this, but only keeps the last parent pattern, thus displaying an invalid path.

The PR fixes the problem by keeping a list of all parent patterns.

Does this happen to relate to this issue I'm having? http://stackoverflow.com/questions/40442468/django-rest-docs-show-wrong-urls?noredirect=1#comment68137074_40442468
