A mistake from implementing this resulted in the shell trying to expand
the 'word' part (e.g. "Line Out"), when the var was unset or null.
Obviously those are are strings and not expandable.

If the env variables in this script are set, use those values. Else it
defaults to using the values set before this patch.
