[wp-hackers] Unexpected behaviour in WP_Query

[Matt Walters]

I asked about it in #wordpress-dev about a month ago and was told
$post->post_category was fine to use for updating a posts categories,
but it does not retrieve the categories when the object is loaded.
So, not sure it really helps with the issue at hand, but just wanted
to point out it's not a complete fossil yet either.
