This is generally no good idea.  I've not implemented this in gettext
since all standards say that exactly one envvar is used.  I.e., LANG
will only be used if LANGUAGE is not available.

Plus, you haven't mentioned LCALL and LC_MESSAGES.  The complete list
of envvars gettext examines is:

	LANGUAGE
	LC_ALL
	LC_MESSAGE
	LANG

in this order.  LANGUAGE is a GNU extension but the rest is standard.

Take a look at the gettext code which also implements the cascading
lookup.
