[issue28128] Improve the warning message for invalid escape sequences

Eric V. Smith added the comment: Also, I assume this is a problem with all such syntax warnings: you only see this warning/error when the file is originally compiled. Once the .pyc file exists, you'll never see a warning or error. Maybe that's okay, but it means there's a certain class of
