The above explanation is nonsense --- the actual cause of the above
behavior is that there is no plain "en_US" locale installed here.

	$ locale -a | grep en
	en_US.utf8
	$ LC_ALL=gobbledegook LANGUAGE=de cp
	cp: missing file operand
	Try `cp --help' for more information.
	$ LANG=en_US.UTF-8 LANGUAGE=de cp
	cp: Fehlendes Dateioperand
	„cp --help“ gibt weitere Informationen.

It _might_ be more intuitive for non-installed locales to enable
LANGUAGE, too; if so, you can pretend I was complaining about that and
call it #4.  Otherwise, please feel free to ignore the example.

Sorry for the confusion.
