Default language environment not calling set-language-environment-hook?

[Matthias Meulien]

I ran emacs with a minimal `~/.emacs' limited to:

(add-hook 'set-language-environment-hook (lambda ()
            (message "Language environment is " 
            current-language-environment))) 

(message "Language environment is " current-language-environment) 


The *Messages* buffer contains: "Language environment is ". But 
when asking for the description of the variable 
`current-language-environment' I get:

Its value is "French" Original value was "English" 

I was expecting the `set-language-environment-hook' to be called. 
Am I wrong?
