[rspec-rails-2] conflict with view isolation and respond_with

Hey all,

For those of you interested in view isolation in controller specs, an
issue has been reported with ActionController’s new respond_with method.
Please take a look at errors when using respond_with instead of respond_to in controller · Issue #103 · rspec/rspec-rails · GitHub and
add comments if you have any thoughts on the matter.

Thanks,
David
