Trying to make split file tests of lex functionality shorter and easier to read. numeric_literals.carbon in particular has an example of why I'm interested in this (at the bottom). This also switches from `[]` list format to `-` list format so that the trailing `]` is removed. Trimming comments in tokenized_buffer.h because (1) it feels like it's giving too much detail about what's printed, which has drifted slightly and (2) it also feels like it's trying to justify YAML output, when that's just what we're doing in general. --------- Co-authored-by: Geoff Romer <gromer@google.com>
