Hi, I bumped my head thrice (yes, thrice!) by using `git bisect bad @`. The error displayed to me at the end of one run was the following: Cela signifie que le bogue été corrigé entre ea3595845f5013359b2ba4402f948e454350a74c et [2e100906d5d0c276335665ffefedb906d21165ca ea3595845f5013359b2ba4402f948e454350a74c]. error: la bissection a échoué : 'git bisect--helper --bisect-state (null)' a retourné le code erreur -3 After the third attempt, I realized: ah yes, computers aren't magic; git-bisect.sh is basically a stupid shell script (no offense!). Perhaps git-bisect.sh can ref-parse the arguments before starting its work? Agreed, none of the refs are expected to change during its operation, with the exception of the sneaky `@`. Bonne année, Ram
