You mentioned in response to my [3/4] review that your accidentally-working write_script() only worked as expected on Mac but not on Windows. When you arrived at this solution of GIT_TEST_CRONTAB="/bin/sh ..." here, was that before or after you fixed write_script() to take the script body from stdin?
