"""A step that could not do its job says so with its exit code.
validate_pr --changed answered "No changed BIOS files detected" and exited
0 when git itself had failed (no origin, or no repository), and
check_buildbot_system --update exited 0 after a refresh it launched had
failed, the cache left at the old version.
