"from the last operation" is not quite right here, it looks like it
re-runs the STATUS command and reports that error?

This should probably also note that it runs a fresh operation.

I was trying to think of a nice way to report the status of the last
operation short of caching it, but I didn't come up with anything
good. I don't think it's important enough to cache, the failure codes
right now are all for things that would persist across runs.
