Well, the reason I was asking was that I was working on a
script where one of the functions will determine the user's
language reliably from the locale settings. Therefore I tried
various error handling, like e.g. the LANG variable not being
set, etc. and I noticed this behaviour and I wondered why. I
see the rule #4 you are referring to, but the logic in it is
still not clear to me: Some script or program might set the
$LANG variable to an empty value and then the LC_* variables
that I set myself will be changed behind my back?

Anyway, thanks for the answer to you and Polytropon.
