The command already supported disassembling multiple ranges, among other reasons because inline functions can be discontinuous. The main thing that was missing was being able to retrieve the function ranges from the top level function object. The output of the command for the case where the function entry point is not its lowest address is somewhat confusing (we're showing negative offsets), but it is correct.
