Tested with your newer branch[1], this time, good news -- from my
minimal testing, no regressions found while running transactional/
non-transactional commands. 

As a transactional subshell test, I ran a three-combination command like
below:

  (QEMU) transaction(
  TRANS> blockdev-snapshot-sync device=drive-ide0-0-0 snapshot-file=./ext-snap2.qcow2 format=qcow2
  TRANS> blockdev-snapshot-internal-sync device=drive-ide0-0-0 name=snapshot1
  TRANS> drive-backup device=drive-ide0-0-0 sync=full target=./backup-copy.qcow2 mode=absolute-paths format=qcow2
  TRANS> )
  {"return": {}}
  (QEMU)

When you submit a new version to the list, FWIW, you can carry my
'Tested-by'.
