`(empty)` change in 4.1

[connortsui20]

Hi, I am going through chapter 4 and I noticed that my terminal output didn't quite exactly match the book.

In 4.1, we add the print functions to src/main.rs, but all future jj log and similar commands have the description (empty) create hello and goodbye functions instead of just create hello and goodbye functions, which I believe means that the added print functions weren't actually added? And I think the later chapters also have the (empty) description. I'm not 100% sure this is incorrect, though it might just be a small point of confusion?

Thanks for the tutorial!

Thanks! It's possible this is just drift, yes.
