 629 More precisely, if an element of this list is a cons of category CAT1\n\

 633 For instance, to tell that ASCII characters and Latin-1 characters can\n\
 634 form a single word, the element `(?l . ?l)' should be in this list\n\
 635 because both characters have the category `l' (Latin characters).\n\
