[wp-hackers] Throw 404 error via plugin

[Will Anderson]

404 isn't a redirect, it's a not found error. These are, for the most part,
completely different problems.

Ryan, when you call set_404() on init, it sets the $wp_query->is_404
variable to true, but when $wp_query is actually constructed (after init),
init_query_flags() is called, which will set $wp_query->is_404 to false
again. You need to hook into pre_get_posts so that your changes to $wp_query
aren't overwritten.
