They all do since yesterday.

Just append [$e] (expand) to the key and $ENV_VARS will automatically be 
expanded.

E.g. if you had:
	hostname=Wantelbos

you can now use
	hostname[$e]=$HOSTNAME

And $HOSTNAME will be expanded at runtime.

For completeness: You can also add [$d] (deleted) to pretend the entry was 
never specified in a config file.

E.g.:
	hostname[$d]

And you can add [$i] (immutable) to mark that an entry may not be modified. 
Immutable and expand can be combined as [$ie] or [$ei].
E.g.:
	hostname[$ie]=$HOSTNAME

Will ensure that the entry can not be modified via KConfig.

Cheers,
Waldo
