It doesn't make sense to talk about "exporting" an environment
variable.

More accurately, parser.c now sets the OVERWRITE environment variable
if either the OVERWRITE GRASS variable is set or if the --o switch is
used. It doesn't modify the OVERWRITE GRASS variable.

Only if the scripts themselves check $OVERWRITE and pass --o to any
commands which they run. G_parser() itself doesn't pay any attention
to the OVERWRITE environment variable.
