--watch should monitor replaced files

What is the problem this feature will solve?

Currently, --watch watches an inode and not necessarily what the user might consider a "file". This can cause confusion on systems that write to disk by deleting the old file and then creating a new one.

For example, when using Docker Compose's watch mode, the watched file is first deleted. When a new file is created Node currently fails to restart on file changes, as node is still watching the inode of the deleted file, and doesn't react to the new file being created.

What is the feature you are proposing to solve the problem?

While this behavior makes sense for the lower-level and more "raw" fs.watch(), perhaps the more general --watch behavior can be expanded to be smarter about detecting replaced files. Alternatively, a new flag can be introduced with this behavior.

What alternatives have you considered?

Other alternatives require using one of the different file watcher libs. That seems like a step down from the otherwise awesome native watch feature.

Comienza con la implementación de --watch de Node.js y el comportamiento de fs.watch descrito en el issue. Reproduce la secuencia de eliminación y recreación al estilo de Docker Compose y, a continuación, determina si el comportamiento existente debe ampliarse o exponerse mediante un nuevo flag. Se considera terminado cuando --watch reacciona de forma fiable al reemplazarse un archivo observado, con cobertura de pruebas para el caso de reemplazo.
