Prevent Wordpress from abbreviating-long-slugs…-in-the-admin

Question

On post edit pages, when a slug exceeds a certain number of characters, Wordpress abridges it with an ellipsis (...). For example, if my slug is i-want-to-be-able-to-see-this-slug, it appears on the edit page like this:

Permalink: http://example.com/2012/i-want-to-be-a...-see-this-slug/ [ Edit ]

Can I prevent Wordpress from doing this?

I like to be able to see (and copy) a full URL without obfuscation, so I'm dying to find out how to get rid with this feature.

Its not possibel via filter or action hook, WordPress cut the strings hard in core. see wp-admin/includes/post.php line 1110 in WP 3.4alpha

if ( function_exists('mb_strlen') ) {
    if ( mb_strlen($post_name) > 30 ) {
        $post_name_abridged = mb_substr($post_name, 0, 14). '…' . mb_substr($post_name, -14);
    } else {
        $post_name_abridged = $post_name;
    }
} else {
    if ( strlen($post_name) > 30 ) {
        $post_name_abridged = substr($post_name, 0, 14). '…' . substr($post_name, -14);
    } else {
        $post_name_abridged = $post_name;
    }
}
