Perhaps you could define a default parameter value for the new parameter of
getRegisteredOptions(...) ? That, or the code example given in the comments
should be fixed.
I think a default parameter value = *cl::TopLevelSubCommand would mean that
no code changes are necessary for downstream users (us ;).
