:use_full_path no longer defaults to true in render from view (2.1.1 regression)

In <= 2.1.0, calling render(:file => ...) from a view defaults the :use_full_path setting to true. Thus, it was possible to render(:file => 'blog/my_widget') from a view, and it would render app/views/blog/my_widget.html.erb as a subtemplate.

In 2.1.1, the above usage broke as a result of this patch: http://github.com/rails/rails/co...

The behavior in 2.1.1 causes use_full_path to effectively default to false for views. Thus, it is now necessary to explicitly set use_full_path in the above example. e.g. render(:file => 'blog/my_widget', :use_full_path => true). I do not believe this was the intent since it entails an API change that wasn't documented in the release notes.

Please find enclosed a simple patch that restores the default of :use_full_path to true. It should be applied against rails/actionpack/lib/action_view/base.rb in the 2-1-stable branch.
