So, '\377' wraps to '\000' and creates a carry of '\001', just as 
'9' wraps to '0' and carries a '1'.  I just thought it might skip 
'\000' (that being the string terminator character and all).  But, 
after looking at the code again, I can see that the literal '\001' 
in there _was_ only meant to serve as the carry.  

Thanks for clearing that up, Pit.
