Thanks!

I suggest that this isNOT the default behaviour.  I think most
peaople would expect that this command only adds/replaces
environment settings, so omitting one value should not cause
unexpected behaviour.

But I agree that such behaviour may also be conveniend - I suggest
that we use an additional option ("-d" ?) to avtiavte it explicitly.

Thanks.

Best regards,
