[Qemu-devel] [PATCH v4 4/5] iotests: implement pretty-print for log and qmp_log |

If iotests have lines exceeding >998 characters long, git doesn't
want to send it plaintext to the list. We can solve this by allowing
the iotests to use pretty printed QMP output that we can match against
instead.
As a bonus, it's much nicer for human eyes too.
