Hi,

When did this work last for you?  I tried every .0 release down to
2.12.0, and all showed this kind of broken output.  (I wasn’t able to
compile 2.11.0 and earlier.)

Here was my test case:

$ ./qemu-img create -f qcow2 foo.qcow2 64M
Formatting 'foo.qcow2', fmt=qcow2 size=67108864 cluster_size=65536 lazy_refcounts=off refcount_bits=16
$ ./qemu-img snapshot -c foofoofoofoofoofoofoofoofoofoo foo.qcow2
$ ./qemu-img snapshot -l foo.qcow2 
Snapshot list:
ID        TAG                 VM SIZE                DATE       VM CLOCK
1         foofoofoofoofoofoofoofoofoofoo      0 2020-01-17 10:53:17   00:00:00.000
$ ./qemu-img --version
qemu-img version 2.12.0 (v2.12.0)

Title:
  qemu-img has broken output with large snapshot names

Status in QEMU:
  New

Bug description:
  On Qemu 4.1.1 the output of snapshots breaks if the chosen state name
  is too long:

  ```
  # qemu-img snapshot -l /mnt/local/some_image.qcow2
  Snapshot list:
  ID        TAG                 VM SIZE                DATE       VM CLOCK
  1         online_provider_with_dhcp747 MiB 2020-01-15 12:05:01   00:00:45.873
  ```

  Prior to 4.1.1 this used to work with extra tabs for the VM SIZE
  values. The collision is also disabling us from using a regex on top
  of this output to detect the snapshot.
