[RFC PATCH v3.1 2/9 2/2] rebase-interactive: Do not automatically run code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



At Junio's suggestion have git-rebase--am and git-rebase--merge work the
same way as git-rebase--interactive. This makes the code more consistent.
