Persistent redirect_to For Login, Registration, and Lost Password

[sparkweb]

Currently, if redirect_to is passed in to the login screen and then a user clicks Register or Lost Password, the redirect_to gets lost. I think that the redirect_to should be persistent and honored whether the user logs in, registers or gets a lost password.

I've written a hacky filter to do this, but I think this ought to be included in the core. Here's what I did:

//Keep redirect_to in URL
add_filter('site_url', 'foxyshop_add_registration_redirect', 5);
function foxyshop_add_registration_redirect($path) {
	if ((strpos($path, "action=register") !== false || strpos($path, "action=lostpassword") !== false) && isset($_REQUEST['redirect_to'])) return $path . '&redirect_to='.urlencode($_REQUEST['redirect_to']);
	if (substr($path, strlen($path)-12) == "wp-login.php" && isset($_REQUEST['redirect_to'])) return $path . '?redirect_to='.urlencode($_REQUEST['redirect_to']);
	return $path;
}

(I know 3.3 is in freeze now, but there wasn't another version option)

The Version is for the earliest version affected by the issue, rather than the one you want it fixed in.
