Rollup merge of #33558 - bnewbold:trivial-book-tweaks, r=steveklabnik
trivial tweaks to documentation (book)
These are small things I found while reading through The Book. The `<hash>` and `panic!` lines are simply to improve readability, while I believe the proceeding/following distinction is a bug (but might be a English dialect distinction?).
I've read `rust/CONTRIBUTING`, i'm not sure if there is anything I need to do other than submit this PR.
