[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.
