I suppose you can get away without doing it, as long as you pay attention
to which of those variables are exported (and so affect other processes'
locale state) and which are not and affect only the shell, and make sure
that the internal and external state is consistent before and after you
do your thing. Bash will reset the state properly for you, but you don't
know what other implementations will do.
