It's already possible if you instantiate the parser yourself instead
of calling the simplified Markdown function:

$parser = new Markdown_Parser;
$parser->fn_id_prefix = $entry_guid;
$text = $parser->transform($text);

And you could add that archives before April 2006 are hard to find:
you have to manually craft the URLs for each months because they are
not in the main list. Two and a half years of discussion are
"missing" like this.
