-git bisect terms [--term-good | --term-bad]
- show the terms used for old and new commits (default: bad, good)
-git bisect skip [(<rev>|<range>)...]
- mark <rev>... untestable revisions.
-git bisect next
- find next bisection to test and check it out.
-git bisect reset [<commit>]
- finish bisection search and go back to commit.
-git bisect (visualize|view)
