[RFC PATCH] rebisect: add script for easier bisect log editing

Add a short script, vaguely inspired by `git rebase --interactive`, to ease the process described in the `git bisect` documentation of saving off a bisect log, editing it, then replaying it.

When I'm bisecting, I find I need to semi-regularly go back and change my good/bad/skip response for some commits. The bisect documentation describes doing this by saving `git bisect log` output, editing it, then using `git bisect replay`. Which is a perfectly fine technique, but automation is A Good Thing(TM). The below script is a short proof of concept for changing this process to be a single command.

Ideally (at least from my perspective), this function would be rolled into the main `git bisect` tool, as `git bisect edit` or similar. Before I start working on that, however, I wanted to see what the list thought of the idea.
