Printf(%q) aka strconv.AppendQuote depends on the Unicode tables du jour, which means gen_test breaks after a Go release in which Unicode evolves. This change uses a very dumb quotation function that emits only ASCII and is independent of the Go release. Perhaps an even better fix would have been to parse the generated file.
