Canonical redirection will redirect a non-exitant page to a post.
|Reported by:||dd32||Owned by:||markjaquith|
Following on from #12601
Canonical redirection will kick in for http://localhost/wordpress-commit/apage/something and redirect it to http://localhost/wordpress-commit/2010/02/13/something-else/
#12601 limited redirect_guess_404_permalink() to only searching in the same post_type if one was provided, for posts and pages however, which are builtin, these vars are not set.
I'm attaching a patch which will prevent a Page -> Post redirection, but not the other way around. - this patch was originally added to the other ticket.
