git-prompt: change the prompt for interactive-based rebases

In the past, we had different prompts for different types of rebases: REBASE: for am-based rebases REBASE-m: for merge-based rebases REBASE-i: for interactive-based rebases It's not clear why this distinction was necessary or helpful; when the prompt was added in commit e752019 ("Improve bash prompt to detect various states like an unfinished merge", 2007-09-30), it simply added these three different types. Perhaps there was a useful purpose back then, but there have been some changes: * The merge backend was deleted after being implemented on top of the interactive backend, causing the prompt for merge-based rebases to 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". Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
