Suppose category X is not empty, and suppose that page [[Category:X]] is a redirect. The contents of category X can still be viewed by appending "&redirect=no" to the url, but even then the "next 200" and "previous 200" links will link to the redirect page itself without "&redirect=no", making it impossible to browse a large category which consists of a redirect (if such thing exists). For an example see http://test.wikipedia.org/w/ index.php?title=Category:Redirecting_category&until=B&redirect=no When clicking the "next 200" link, the target of the redirect is loaded instead.
This appears to be fixed per your example working as expected, with the prev and next links preserving &redirect=no. Marking worksforme.
