Would that be land-able? It's in contrib, so personally I don't care much. But e.g. on OSX that means targeting some ancient (and going away?) version of bash + having *BSDs needing to install bash for this etc. Bash or not it seems to me like that argument parsing code could be much simplified by simply declaring strings of arguments accepted for each sub-command, and then parsing those arguments + dying on unknown ones.
