Fast Downward currently accepts "cost_type=" without a valid cost type. Is this 
a bug or a feature?

./downward-2 --heuristic "hAdd=add(cost_type=)" --search 
"lazy(alt([single(sum([g(),weight(hAdd, 7)])),single(sum([g(),weight(hAdd, 
7)]),pref_only=true)], boost=0),preferred=[hAdd],reopen_closed=true,cost_type=)"
