Whether useful or not, a bug or a feature, something must be done;  
because the average user is helpless when something invisible for him  
appears at the very beginning of his file, before he can even write  
anything. The catcode change must be in the format file so that when  
the first bytes of the TeX file are read, they can be ignored.
