Wow. Good find.

I wonder if we could simultaneously verify these "expected" results match
using another command without the untracked cache? It's good that we have
the expected outputs explicitly, but perhaps double-checking the command
with `-c core.untrackedCache=false` would help us know these are the correct
expected outputs?
