I suspect that a "-" in place of a commit object name may not be
enough for your purpose, as the _number_ of parents can later
change in the later re-output.

I wonder if the presense of "incomplete" on the "Final output"
line is a good enough indication for that.  That is, until you
see "Final output: $N done", you will treat the parent
information as unreliable.
