"Trash" should not be a bulk action when user can't delete a post at all

[markoheijnen]

When a user can't delete posts at all for a certain post type the bulk action to delete posts is useless.

Not sure if the following check is correct:

		if ( current_user_can( $post_type_object->cap->delete_post ) ) {
			if ( $this->is_trash || !EMPTY_TRASH_DAYS )
				$actions['delete'] = __( 'Delete Permanently' );
			else
				$actions['trash'] = __( 'Move to Trash' );
		}

Maybe the edit/restore functionality should have some similar check

delete_posts should be plural. Otherwise, seems good at a glance.

I just stumbled upon this too. Patch looks good.

In 29757:

If the current user does not have the delete_posts cap on the current post type, don't list delete or trash as bulk actions for the relevant context of Post list table.

Props mvd7793.
Fixes #20175.
