The statement you're referring to only affects tcsh, not bash. But
you're right, nevertheless. I would simplify this to
/etc/profile.d/lang.csh:
if ( $?LC_ALL == 0 && $?LC_CTYPE == 0 && $?LANG == 0 ) setenv LANG C.UTF-8
This works without forking any child process. And the user might
actually want to set one of these variables to an empty string.
