[Tutor] A problem in read_until(expected[,timeout])

I think this should work:
	obj.read_until(timeout=10)	# no expect string
	obj.read_until("ten",10)	# "ten" or 10 seconds

read_until is a method of the telnet object so your code should have the
name you gave the telnet object before the read_until.  I used obj
simply to indicate there should be some name there.

The documentation can be confusing because it uses [] to mark optional
parameters while Python uses [] to mark lists.

When you do not need all of the arguments, you can specify the names of
the arguments that you want to use.  That's why timeout=10 should work
in the first suggestion.
