[09/11] rebase: use our standard error return value

Commit Message

From: Phillip Wood <[e-mail]>

Git uses −1 to signal an error. The builtin rebase converts these to
+1 all over the place using !! (presumably because the in the scripted
version an error was signalled by +1). This is confusing and clutters
the code, we only need to convert the value when the function returns.
