rebase -i: do not "echo" random user-supplied strings
In some places we "echo" a string that comes from a commit log message, which may have a backslash sequence that is interpreted by the command (POSIX.1 allows this), most notably "dash"'s built-in 'echo'. A commit message which contains the string '\n' (or ends with the string '\c') may result in a garbage line in the todo list of an interactive rebase which causes the rebase to fail. To reproduce the behavior (with dash as /bin/sh): mkdir test && cd test && git init echo 1 >foo && git add foo git commit -m"this commit message ends with '\n'" echo 2 >foo && git commit -a --fixup HEAD git rebase -i --autosquash --root Now the editor opens with garbage in line 3 which has to be removed or the rebase fails.
