Update procedure in Drupal 8 - dangerous cp statement

I'm brand new here, so apologies in advance :)

https://www.drupal.org/docs/8/update/update-procedure-in-drupal-8
(which is locked, correct?)

Step 5:

As someone else has already pointed out in the comments, this statement causes a loop:

cp -Rf drupal-x.y.z/* drupal-x.y.z/.* /path/to/your/installation

(it'll keep copying and you'll end up with /path/to/your/installation/installation/installation/… plus the contents of all directories on the same level.)

I assume it ought to be:

cp -Rf drupal-x.y.z/* /path/to/your/installation/
cp -f drupal-x.y.z/.* /path/to/your/installation/

(Honest opinion: as a new user, this page is pretty hard going, indeed I still haven't managed to successfully complete it yet, although I'm trying to upgrade an Acquia Desktop installation which complicates things a little.)

Thanks,
William
