The original code still needed some adapting from the original Go version. Specifically: - it looked for semicolons not commas - it recognized the Go backquoted string syntax - it recognized the Go /*...*/ comment syntax Also, make it a little less general, as currently we don't seem to need the import-saving functionality (we can use `parser.ParseFile` with `CommentsOnly` which will keep us honest, even at a little bit of runtime cost), and because of that, we don't need to try to detect syntax errors. We can optimize at a later date if need be.
