Consider this history: o--o-...-B <- origin \ \ x--x--M--x--x <- master In this situation, rebase considers master fully up-to-date and would not do anything. However, if there were additional commits on origin, the rebase would run and move the commits x on top of origin. Here we change rebase to short-circuit out only if the history since origin is strictly linear. Consequently, the above as well as a history like this would be linearized: o--o <- origin \ x--x \ \ x--M--x--x <- master Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at> Signed-off-by: Junio C Hamano <gitster@pobox.com>
