This is really good... but you can do even better.

The filter passes in a lot more useful info.

(follow code is untested even by a php interpreter)

add_filter('gettext', 'rss_title_prefix', 10, 3)

function rss_title_prefix($translation, $original, $domain) {
	if ( ( 'default' == $domain ) && ('Comments on: %s' == $original) {
		return get_bloginfo('name') . ' - ' . $translation;
	}
	return $translation;
}


This will ensure you match the exact string (and it works for any  
language.
