 If someone wanted to add an argument for easy filtering on a taxonomy and
 then used get_taxonomies to query that non-standard key, it generates
 notices.

 E.g., Given labels,

 {{{
 $args = array( 'mycustomkey' => true, 'hierarchical' => 0, 'rewrite' =>
 array( 'slug' ), );
 register_taxonomy( 'my_taxonomy', array( 'my_post_type' ), $args);
 }}}


 Then later, if I used:

 {{{
  get_taxonomies( array( 'mycustomkey' => true ) );
 }}}

 it generates:

 {{{
 Notice: Undefined index: mycustomkey in C:\xampp\htdocs\www\sandbox\wp-
 includes\functions.php on line 2499.
 }}}


 This is a simple fix:
 {{{
 if ( isset($to_match[ $m_key ]) && $m_value == $to_match[ $m_key ] )
 }}}
