-/**
- * Accepts any node Stream instance and hijacks its "write()" function,
- * so that it can count any newlines that get written to the output.
- *
- * When a '\n' byte is encountered, then a "newline" event will be emitted
- * on the stream, with no arguments. It is up to the listeners to determine
- * any necessary deltas required for their use-case.
- *
- * Ex:
- *
- * var cursor = ansi(process.stdout)
- * , ln = 0
- * process.stdout.on('newline', function () {
- * ln++
- * })
