7329 - snapshot: advent day 4 part 2
I've found two bugs in SubX libraries: 1. next-word had an out-of-bounds read 2. next-word was skipping comments, because that's what I need during bootstrapping. I've created a new variant called next-raw-word that doesn't skip comments. These really need better names. We're now at the point where 4b.mu has the right structure and returns identical result to 4a.mu.
