Why the device of quartus_cpf command is illegal?

As noted in the earlier post, on Quartus 13.0sp1 I use a configuration file .cof and run quartus_cpf -c design.cof and that works just fine.

You just have to put all the parameters in the .cof file and not on the command line.

Contents of my design.cof file:

<?xml version="1.0" encoding="US-ASCII" standalone="yes"?>
<cof>
