Comment (by jtsternberg):

 In [http://core.trac.wordpress.org/attachment/ticket/21240/21240.4.diff
 21240.4.dff] I added

 {{{
 $this->taxonomy_columns = apply_filters( 'show_taxonomy_columns',
 $taxonomies, $post_type );
 }}}

 This line allows plugins and themes to filter the taxonomy columns. i.e.
 {{{
 add_filter( 'show_taxonomy_columns', 'add_resource_category_column', 10, 2
 );
 function add_resource_category_column( $tax_columns, $post_type ) {
         if ( $post_type == 'resources' ) $tax_columns[] = 'session-
 audiences';
         return $tax_columns;
 }
 }}}

 This allows taxonomies registered after the fact to add their columns to
 post-types.
