[Texdoc 3.4.1 (2022-03-19), without personal configuration file]

How is language-specific documentation selected?  For example, the
default language environment settings on my GNU/Linux box are


Doing one of the following

texdoc impnattypo
LANGUAGE=en texdoc impnattypo

however, displays `impnattypo-fr.pdf`.  I have to say

LANG= texdoc impnattypo

to eventually get `impnattypo.pdf`.

This behaviour doesn't look right to me.  Why is the `LANGUAGE`
setting ignored?  And, more severe: Why is `LANG=en_US.UTF-8` ignored?
