Yes. Setting LC_ALL does that too, but the difference between LC_ALL
and LANG is that LC_ALL takes precedence over the specific LC_xxx
variables, whereas LANG does not. Hence, LANG allows you to set all
locale categories while still allowing specific ones such as
LC_COLLATE to be overridden. (Perhaps things would be a bit clearer if
LANG had been called LC_DEFAULT or some such.)
