wp_list_pages(): pass args $r to apply_filters()

[antonylesuisse]

A one line fix:

- $output = apply_filters('wp_list_pages', $output);
+ $output = apply_filters('wp_list_pages', $output, $r);

It would allow filters to test clauses such as 'child_of==0'.

I currently use the following hack in the filter function:
$bt=debug_backtrace();
$r=$bt[3]["args"][0];

just checking... have you looked into the widget_pages_args hook?

adding to this, if we pass one argument, we should really pass them all as an array.

Replying to Denis-de-Bernardy:

line 745:

$r = wp_parse_args( $args, $defaults );

$r is already the right array.

my bad, it's late. Thought $r was shorthand for the return param. :P

still applies clean
