Extra brake tags in get_the_password_form

Here’s the get_the_password_form() function from post-template.php

function get_the_password_form() {
	global $post;
	$label = 'pwbox-'.(empty($post->ID) ? rand() : $post->ID);
	$output = '<form action="' . get_option('siteurl') . '/wp-pass.php" method="post">
	<p>' . __("This post is password protected. To view it please enter your password below:") . '</p>
	<p><label for="' . $label . '">' . __("Password:") . ' <input name="post_password" id="' . $label . '" type="password" size="20" /></label> <input type="submit" name="Submit" value="' . esc_attr__("Submit") . '" /></p>
	</form>
	';
	return apply_filters('the_password_form', $output);
}

Here’s my output

<form method="post" action="http://192.168.1.101/wp31/wp-pass.php">
<p>This post is password protected. To view it please enter your password below:</p>
<p><label for="pwbox-115">Password:<br>
<input type="password" size="20" id="pwbox-115" name="post_password"></label><br>
<input type="submit" value="Submit" name="Submit"></p></form>

See the two brake tags, one after “Password:” and the other after </label>? Where do they come from?
