Is there anything you'd like reviewers to focus on?
When reporting the location for a linefeed, there is two reasonable way to do so, the first is to report {start: {line: m, column: n}, end: {line: m, column: n 1}}. This approach does not work in VSCode. The second way is to report {start: {line: m, column: n}, end: {line: m 1, column: 0}}. This does work in VSCode, except for when that start location is the location of EOF. In that case I chose to not report end location.
