The revert fixed the problem - thanks for the suggestion!

I will understand if it turns out we cannot guarantee output format
from release to release - I am not sure what the options are with the
underlying issue(s).

If for some reason this cannot be fixed up, and output needs to change,
maybe at least describe how output will change in the commit message.
It's not fully clear what happened in this automation - I didn't get a
chance to track down what happened as it only occurred in certain
vmcores and possibly with certain sequences of commands.

Let me know if you want further testing.
