I think I can do that, since I raised that same question this past weekend.

On or around line 64 in _item_content.inc.php you will see

	$Item->more_link( array(
		'before'    => $params['before_more_link'],
		'after'     => $params['after_more_link'],
		'link_text' => $params['more_link_text'],
		) );

Add one line so it looks like this:

	$Item->more_link( array(
		'before'    => $params['before_more_link'],
		'after'     => $params['after_more_link'],
		'link_text' => $params['more_link_text'],
		'anchor_text' => ' ',
			) );

I copied the file into /skins/myskin to make sure I kept the change.
