docs: Registers a flag whose value is a whitespace-separated list of strings.
  
    Any whitespace can be used as a separator.
  
    Args:
      name: str, the flag name.
      default: list|str|None, the default value of the flag.
      help: str, the help message.
      comma_compat: bool - Whether to support comma as an additional separator.
          If false then only whitespace is supported.  This is intended only for
          backwards compatibility with flags that used to be comma-separated.
      flag_values: FlagValues, the FlagValues instance with which the flag will
          be registered. This should almost never need to be overridden.
      **args: Dictionary with extra keyword args that are passed to the
          Flag __init__.
