    generally it's easier to just go "back in time" and re-try the last
    known "good" and last-known "bad" commit IDs to establish that they are
    indeed correctly identified. if they are not then step back one more in
    the bisection log. No need to spend another 4 days on this, if most of
    the bisection is OK. You can replay a corrected git bisection log
    quickly, by doing:

    git-bisect reset
    git-bisect < bisect.log
