Re: [PATCH v2 11/15] contrib: change the prompt for interactive-based rebases

> From: Elijah Newren <newren@gmail.com>

>     change from REBASE-m to REBASE-i.
>   * The interactive backend is used for multiple different types of
>     non-interactive rebases, so the "-i" part of the prompt doesn't
>     really mean what it used to.
>   * Rebase backends have gained more abilities and have a great deal of
>     overlap, sometimes making it hard to distinguish them.
>   * Behavioral differences between the backends have also been ironed
>     out.
>   * We want to change the default backend from am to interactive, which
>     means people would get "REBASE-i" by default if we didn't change
>     the prompt, and only if they specified --am or --whitespace or -C
>     would they get the "REBASE" prompt.
>   * In the future, we plan to have "--whitespace", "-C", and even "--am"
>     run the interactive backend once it can handle everything the
>     am-backend can.
> 
> For all these reasons, make the prompt for any type of rebase just be
> "REBASE".
