I created a custom markup for the categories.  A page variable may  
have been easier.  I was desperate for something that worked, so I  
hacked a new markup [[?PageName | Name of Link]] to strip out the  
periods (and any other nasty not-page-name-friendly characters):

// The following markup fixes a problem when retrieving data with  
periods
// to create category page markup.
Markup('[[?','<[[!','/\\[\\[\\?([^\|]*)\|?(.*?)\\]\\]/e', "Keep 
(MakeLink(\$pagename,PSS(helpXES('$CategoryGroup/$1')),PSS('$2'),'',\ 
$GLOBALS['LinkCategoryFmt']),'L')");
function helpXES($param) {
	$param = preg_replace('/[^A-Za-z0-9 -]/', '', $param);
	return  $param;
}

and added that to config.php.

I may have introduced other bugs to the program, so I'm more than  
willing to hear alternatives :)
