**Use case**
Some program left garbage in terminal.

**Describe the solution you'd like**
Subset of what `reset` command does.
std::cout << st << st;
        }
        return res;
    }
    void sendData(Block & sample, const ColumnsDescription & columns_description)
    
        /// If INSERT data must be sent.
        aut_query->as<ASTInsertQuery>();
        if (!parsed_insert_query)
            return;
        if (parsed_insert_query->data)
        
            /// Send data contained in the query.
            rsed_insert_query->data, parsed_insert_query->end - parsed_insert_query->data);
            try
            
                sendDataFrom(data_in, sample, columns_description);
            }
            catch (Exception & e)
            
                /// The following query will use data from input
                //      "INSERT INTO data FORMAT TSV\n " < data.csv
                //  And may be pretty hard to debug, so add information about data source to make it easier.
                e.addMessage("data for INSERT was parsed from query");
                throw;
            }
            // Remember where the data ended. We use this info later to determine
            // where the next query begins.
