path-util: document that we shouldn't add further entries to hidden_or_backup_file()
And let's add ".bak" as a generic suffix for backups, that people can use without having to register their stuff in our list.

+ * The generic suffixes "~" and ".bak" for backup files
+ * The generic prefix "." for hidden files
