If you wanted to add right double angle quotes or raquo to each of your comment block comments. First you would track down the functionality that needs changing to theme_comment_block() inside the comments module ..

function theme_comment_block() {
$items = array();
$number = variable_get('comment_block_count', 10);
foreach (comment_get_recent($number) as $comment) {
$items[] = l($comment->subject, 'comment/' . $comment->cid, array('fragment' => 'comment-' . $comment->cid)) . ' ' . t('@time ago', array('@time' => format_interval(REQUEST_TIME - $comment->changed))) . '';
}
if ($items) {
return theme('item_list', array('items' => $items));
}
else {
return t('No comments available.');
}
}

function comment_block_view($delta = '') {
if (user_access('access comments')) {
$block['subject'] = t('Recent comments');
$block['content'] = theme('comment_block');
return $block;
}
}

and then make your changes by overriding theme_comment_block inside your theme's template.php as ..

function mytheme_comment_block() {
$items = array();
$number = variable_get('comment_block_count', 10);
foreach (comment_get_recent($number) as $comment) {
$items[] = l('» ' . $comment->subject, 'comment/' . $comment->cid, array('fragment' => 'comment-' . $comment->cid, 'html' => true)) . ' ' . t('@time ago', array('@time' => format_interval(REQUEST_TIME - $comment->changed))) . '';
}
if ($items) {
return theme('item_list', array('items' => $items));
}
else {
return t('No comments available.');
}
}

After clearing the cache your theme function will be now called instead of the theme function provided by the core comment module.
