rebase: do not continue when the todo list generation failed

This is a *really* long-standing bug. As a matter of fact, this bug has
been with us from the very beginning of `rebase -i`: 1b1dce4bae (Teach
rebase an interactive mode, 2007-06-25), where the output of `rev-list`
was piped to `sed` (and any failure of the `rev-list` process would go
completely undetected).
