<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Better default values in `WP_Query::get_queried_object()`.
Setting the default value of the `queried_object_id` property to `0` meant
that, when called early enough in the WP bootstrap, `get_queried_object()`
could short-circuit the normal query by fooling it into thinking that the
request was for a page with id 0. Setting the default value to `null` instead
avoids this problem.
Props gradyetc, jazbek.
