Option to turn off rewrite with_front?

Hi,

We have out permalinks setup as /blog/%postname%/ (The blog used to be wordpress in a sub-folder so we moved it to the root and changed the permalinks so the blog post urls stay the same).

When I create custom post types I turn the “rewrite with front” option off which removes the /blog/ part from the url.

I overrode the plugins custom post type with the register_post_type_args filter to turn front off.

That works for the test pages which then have urls like /test/test-name but it breaks the results page which shows a 404 error.

Can you add an option to turn off the front setting so that the results pages still work?
Or is there another way I can get it working with the nice urls and working results page?
