[theme-reviewers] home_url('/') VS esc_url(home_url('/')) Clarification

[Chip Bennett]

He's talking about this, I think:

http://core.trac.wordpress.org/browser/tags/3.6.1/wp-includes/formatting.php#L2660

The value returned by esc_url() is filtered:

return apply_filters('clean_url', $good_protocol_url, $original_url,
$_context);


There are a lot of rabbit holes...
