FORMAT JSON

{
	"meta":
	[
		{
			"name": "1",
			"type": "UInt8"
		}
	],

	"data":

The issue appears only in interactive mode. In non-interactive mode clickhouse-client produces the correct output:

```
# clickhouse-client -q 'select 1 format JSON'

	"meta":
	[
		{
			"name": "1",
			"type": "UInt8"
