[Plugin: Google XML Sitemaps] Doesn't support custom post types with dashes

I’ve just started using this plugin (4.0beta8) and I’ve noticed it relies heavily on dashes — unfortunately, if your custom post type has dashes in it, they don’t show up in XML files. This specifically happens in GoogleSitemapGeneratorStandardBuilder::BuildPosts() here:

if(!$pts = strpos($params, "-")) return;
$postType = substr($params, 0, $pts);

If my post type is featured-projects then $postType becomes ‘featured’.

To fix this, I’ve changed this method from:

if(!$pts = strpos($params, "-")) return;

$postType = substr($params, 0, $pts);

if(!in_array($postType, $gsg->GetActivePostTypes())) return;

$params = substr($params, $pts + 1);

global $wp_version;

if(preg_match('/^([0-9]{4})\-([0-9]{2})$/', $params, $matches)) {
	$year = $matches[1];
	$month = $matches[2];
	# ... lots of other code...
}

to:

if (!preg_match('/^(.*)-(\d{4})-(\d{2})$/', $params, $matches)) return;

$postType = $matches[1];

if(!in_array($postType, $gsg->GetActivePostTypes())) return;

global $wp_version;

$year = $matches[2];
$month = $matches[3];
# ... lots of other code...

Here is a gist of the full file: https://gist.github.com/1775697

Thus far, this has resolved this issue for me. However, since dashes are relied upon in other places, I would wage that there are other similar issues elsewhere in the plugin. Please let me know if I can be of any assistance in resolving any other issues.
