qemu-img snapshot -l output formatting is broken (field to small / whitespace missing)

Host environment

Snapshot list:

ID TAG VM SIZE DATE VM CLOCK ICOUNT

Description of problem:

when listing a snapshot, qemu-img does not correctly format output, as you can see between DATE and VM CLOCK , there is no whitespace between the numbers. i found no way to add formatting option for correct output.

furthermore, using whitespace in column headers does make it hard to read/decide if "VM SIZE" or "VM CLOCK" are tags or "VM" is different column, especially when output is not formatted according to header.

what about adding "VM_SIZE" and "VM_CLOCK" and "n/a" when there is no output (ICOUNT) ?
