The request was for the latter: "just make it stronger in the mentioned line that what was called previously 'option' is now called 'args'".

As far as adding the parentheses or not, I never once used the parentheses back when I was using optparse, so it didn't even strike me to put them in there. But you're right - the optparse docs do that, so I'm fine if you'd like to make the argparse discussion of optparse match up better with the optparse docs.
