Okay, so what would the interface look like? I think it'd better to separate the option and pass column and (optional) sort key argument. --cumulative both,total (default) --cumulative both,self --cumulative total --cumulative self (meaningless?) Maybe we need a config option and a single letter option for the default case like --call-graph and -g options do. What do you think?
