Hi guys, i'm implementing a plugin for rewriting post slugs.
i noticed that reading the source code of the register_post_type function, there is no filter before the args are parsed. It could be usefull to have the filter to modify some custom post types on the fly. The 'registered_post_type' filter act only after the permastruct and the rewrite rules are done.
So for example you could act as above inside the register_post_type function:

if ( strlen( $post_type ) > 20 ) {
		_doing_it_wrong( __FUNCTION__, __( 'Post types cannot exceed 20 characters in length' ), '4.0' );
		return new WP_Error( 'post_type_too_long', __( 'Post types cannot exceed 20 characters in length' ) );

apply_filters( "registering_post_type", $post_type, $args);

// If not set, default to the setting for public.
if ( null === $args->publicly_queryable )
	$args->publicly_queryable = $args->public;

the filter needs to return the $args modified;

so the correct line is

$args = apply_filters( "registering_post_type", $post_type, $args);
