Post_type + non-existant object + Canonical

[dd32]

Hit a page such as this: ​http://localhost/wordpress-commit/wiki/something and the canonical system kicks in and attempts a redirect to ​http://localhost/wordpress-commit/2010/02/13/something-i-want-to-keep-quiet/

The canonical system should reconise when a object being queried is a post_type and not redirect to a similar slug.

The same redirection will take place for the url ​http://localhost/wordpress-commit/apage/something - Once again, redirection from page -> post.

• Limits to searching for posts in the same post_type if a post_type was specified in the original rewrite rule.
• Does not apply to the Page -> Post redirection, Only to Custom Post Type -> Other Post type redirection

(In [13697]) Limit redirect_guess_404_permalink() to the same post_type if it's specified in the query. See #12601

• Needs Testing.

• If a request is for a Post (ie. /2008/12/somethi), then the 404 search will only look for posts with 'somethi%'
• If a request if for a Page (ie. /somethi), then the 404 search will look at both pages AND posts

Its a step forward IMO, but still doesnt prevent page -> post redirects. It nearly seems like leaving that functionality present would be best, while avoiding the obviously incorrect redirects from post permalinks to pages.

Closing this as fixed for 3.0, created #13041 to carry on the Page -> Post -> Page redirections.
