>Description:

	The commandline is not parsed very accurately, and this can
	produce bogus results. Also, it is non-obvious how to remove
	a lock (omit the -lock keyword and specify the value 0).

>How-To-Repeat:

	try the following:

	root# route change default -lock                 # does nothing
	root# route change default -lock -mtu            # segmentation fault
	root# route change default -lock -mtu garbage    # -lock -mtu 0
	root# route change default -mtu                  # segmentation fault
	root# route change default -mtu garbage          # -mtu 0

>Fix:
	
	don't rely so heavily on atoi() to DTRT
