This is a typo fix. I have read the contributing guidelines that advise against typo fixes (specifically: "these will almost certainly be caught during the editing process"). However, I feel justified in submitting a PR for this one because it made it through the editing process to my printed copy of the second edition! Great book BTW. If I come across any other typos I will add them as additional commits to this PR.
Typos?
Please don't worry about minor text typos. These will almost certainly be caught during the editing process.
If you're going to submit a PR for typo fixes, please be measured in doing so by collecting several small changes into a single PR (in separate commits). Or, just don't even worry about them for now, because we'll get to them later. I promise.
