Log Message:
make(1): migrate Var_Parse API to parsing position
The ApplyModifier functions already use this pattern. For simplicity
and consistency Var_Parse should do the same. This saves a parameter to
be passed.
The migration takes place step by step, just like for the Lst functions
a few days ago.
