But no matter how hard I search for it again, all I come up with is that "cat" *should* work with comma-separated values. But it just searches the first and ignores the rest. Even if I manually type in the categories to search, it still ignores all ID's but the first one.

Well first suggestion is to try debugging this via your search.php template. Dump the $wp_query. Check to see it the categories are being set. Also, might want to try adding this via a filter. Inside that function you should be able to grab you form variable and make sure it uses your search terms. Of course per other suggestions you can change the 'cat' to 

function mySearchFilter($query) 
   if ($query->is_search)
   return $query;
