Hmm. I was worried that this would make it harder to turn the output of
"git bisect log" into something you can inject into "git bisect replay
<log>". But it doesn't, because you prefix the status lines with a '#'
character.
That's good, and I think it's an improvement over what I'd currently
recommend, which would be something like:
git bisect log | grep '^# bad:'
git bisect log | grep '^# good:'
to see the state of our good and bad endpoints.
I'm not totally convinced it _needs_ to live in "git bisect log",
though, since it feels like additional information that is just added
for convenience. That's not the worst thing in the world, but I think
it would be fine to just take the first patch (with my suggestions
applied) as well.

This direct use of vsnprintf might be avoided by preparing the output in
bisect_print_status() via a strbuf and then calling:
append_to_file(git_path_bisect_log(), "# %s", buf.buf).

Interesting; this patch removes the output that we were giving to users
in the last patch. Should it go to both places?
Thanks,
