The importmulti help text reads, in part: 

```
{                                                          (json object) If a ranged descriptor is used, this specifies the start and end of the range to import
           "start": n,                                              (numeric, optional, default=0) Start of the range to import
           "end": n,                                                (numeric, required) End of the range to import (inclusive)
},
```

This is a value for which a key is missing; it should be "range": { ...
if (new_line_pos == std::string::npos) {
                    break; 
                }
                right += "\n" + std::string(pad, ' ');
                begin = s.m_right.find_first_not_of(' ', new_line_pos + 1);
                if (begin == std::string::npos) {
                    break; 
                }
                new_line_pos = s.m_right.find_first_of('\n', begin + 1);
            }
            ret += right;
            ret += "\n";
        }
        return ret;
    }
};
