'not_found' taxonomy label should be used in the list table

[iammathews]

When registering a new taxonomy, you cannot change the "No items found." label when there are no items for that specific taxonomy.

[SergeyBiryukov]

There is a 'not_found' argument​ for taxonomy labels, see #23597 where it was introduced.

As read on the codex - 'not_found' (3.6+) - the text displayed via clicking 'Choose from the most used tags' in the taxonomy meta box when no tags are available. This string is not used on hierarchical taxonomies.

It's as if 'not_found' gets ignored. Here's the code:

add_action( 'init', 'register_programme_types', 0 );
function register_programme_types(){
	$labels = array(
		'name'              => _x( 'Programme Types', '' ),
		'singular_name'     => _x( 'Type', '' ),
		'menu_name'         => __( 'Programme Types' ),
		'all_items'         => __( 'All Types' ),
		'edit_item'         => __( 'Edit Type' ),
		'view_item'         => __( 'View Type' ),
		'update_item'       => __( 'Update Type' ),
		'add_new_item'      => __( 'Add New Type' ),
		'new_item_name'     => __( 'New Type Name' ),
		'parent_item'       => __( 'Parent Type' ),
		'parent_item_colon' => __( 'Parent Type:' ),
		'search_items'      => __( 'Search Types' ),
		'not_found'         => __( 'No types found.' ),
	);

	$args = array(
		'hierarchical'      => true,
		'labels'            => $labels,
		'show_ui'           => true,
		'show_admin_column' => true,
		'query_var'         => true,
		'rewrite'           => array( 'slug' => 'types' ),
	);

	register_taxonomy( 'types', array( 'programmes' ), $args );
}

I've noticed this before. As iammathews points out, it's not used on non-hierarchical taxonomies. I started patching this once before and must have gotten distracted.

[SergeyBiryukov]

Well, it's not used in the list table, regardless of whether the taxonomy is hierarchical.

30586.patch​ fixes that.

In 31035:

Use the 'not_found' label when there are no items for a taxonomy in the terms list table.

Props SergeyBiryukov.
Fixes #30586.
