All locale_config does is write the chosen locale setting to
/etc/sysconfig/i18n under string 'LANG'.
One could argue locale is a lot more than just 'LANG'.
Configuring locale settings (including, but not limited to LANG) should be
more flexible, perhaps being able to set other locale-settings too, coupled
with descriptions what they actually do.
