I still don’t know about 055, but for 028 it looks like a race.

We have this:

> _send_qemu_cmd $h "drive_backup disk ${TEST_IMG}.copy" "(qemu)" >/dev/null
> _send_qemu_cmd $h "" "Formatting" | _filter_img_create

But it looks to me like the “Formatting” line comes earlier when the
path is longer.  No, I don’t know.

What I do know is that this looks wrong altogether.  Why would the
(qemu) prompt necessarily appear before the “Formatting” message?  I
think the drive-backup job creates the image before it is guaranteed to
yield.

So I think the solution is to s/(qemu)/Formatting/ in the expected
return value, replace the “"" "Formatting"” line by “"" "(qemu)"”, and
drop the “Formatting” output from the reference output.  (And add an
empty “(qemu)” line to the reference output.)
