This ensures that the editor is never consulted?  How?  Running the
"false" editor would give us a different error, like "your editor
exited with non-zero status, telling us to abort" or something?

Yup, exactly that. We'd see "Aborting commit as launching the editor
failed." instead of the above error message.
