Thanks for the contribution @OzNetNerd ! A couple of things:

1. I think what you're intending this to do is to have the limit parameter operate on the list operation as a whole, which on reflection makes more sense than what it's currently doing, which is setting the page size using the API's limit query parameter. However, it's not really properly doing that. What it should be doing instead is keeping track of how many items have been yielded and stopping the loop after limit items have been produced. Make sense?
2. Could you please re-word the commit message to fix the typo? It will make searching history easier for future folks.
