Ah, I see.  When I specified it with a space, I see that all order  
kndiscount were set to 1:

  kndiscount1=1 kndiscount2=1 kndiscount3=1 kndiscount4=1  
kndiscount5=1 kndiscount6=1 kndiscount7=1 kndiscount8=1 kndiscount9=1

-- and with -kndiscount5 I get

  kndiscount1=0 kndiscount2=0 kndiscount3=0 kndiscount4=0  
kndiscount5=1 kndiscount6=0 kndiscount7=0 kndiscount8=0 kndiscount9=0

-- so apparently it ignores the trailing five and does a full KN model  
if there's a space, right?  I'm after the "full" KN model as per Chen  
& Goodman -- so should I just say -kndiscount without any numbers to  
get it, with -order 5 for 5-grams maximum?
