[docs] Pedantic word change (http://docs.python.org/2/tutorial/classes.html#generators)

[Tama Pugsley]

Hi there,

I'm just getting started with Python (escaping PHP madness), thanks for 
writing such awesome documentation.

Quick tense change here:
http://docs.python.org/2/tutorial/classes.html
9.10. Generators

"Another key feature is that the local variables and execution state are 
automatically saved between calls. This >>>made<<< the function easier 
to write and much more clear than an approach using instance variables 
like self.index and self.data."

Should the second sentence start "This MAKES"?

Cheers,
Tama
