What if you forget `--diff`?

If you forget to use --diff, it is not easy to see what has changed. Some modules like the copy and template modules have a backup option. If you set this option, then it will keep a backup copy next to the destination file.

However, most modules do not have such an option, so if you want to know what changes, always use --diff.
