[wp-hackers] Custom Taxonomy Query - Select posts with a taxonomy AND none

[Alex Hempton-Smith]

There's not really a code snippet to post. Perhaps I can phrase it
differently; can I have WP_Query return posts which match the taxonomy term
searched for (usual behaviour), and posts which have NO terms for that
given taxonomy?

So if I search for 'foobar' it would return posts where $mytax == 'foobar'
and $mytax == '' (empty)
