Extra spaces in wp_title

[nbspjr]

Greetings.
wp_title adds extra spaces to the title even if separator is set to be empty. The spaces are added on the side where separator's location is set. For example, if I have title "Blog", then wp_title(""); will output " Blog" and wp_title("", "right"); - "Blog ". At this moment I have to call 'wp_title' filter to trim spaces if there is empty separator passed, something like this:

function my_wp_title($title, $sep, $loc) {
  return ( empty($sep) ) ? trim($title) : $title;
}
add_filter('wp_title', 'my_wp_title', 10, 3);

What do you think of enhancing wp_title function to not add spaces if there is an empty separator?
