More filters in user.php

[hughwillfayle]

In the wp-includes/user.php there should be some more filters in the function prepare_query().

e.G. before the line

$this->query_where .= $this->get_search_sql( $search, $search_columns, $wild );

this

$search_columns = apply_filters( 'user_list_search_columns', $search_columns );
$this->query_where .= $this->get_search_sql( $search, $search_columns, $wild );

Also, in the sorting block:

$orderby = apply_filters( 'user_list_search_order_by', $orderby );

All parts of the query can be changed through the 'pre_user_query' action.
