These patches correspond to a fourth part of patch series 
of Outreachy project "Finish converting `git bisect` from shell to C" 
started by Pranit Bauva and Tanushree Tumane
(https://public-inbox.org/git/pull.117.git.gitgitgadget@gmail.com) and
continued by me.

This fourth part is formed by reimplementations of some `git bisect` 
subcommands, addition of tests and removal of some temporary subcommands.

These patch series emails were generated from:
https://gitlab.com/mirucam/git/commits/git-bisect-work-part4-v6.

I would like to thank Johannes Schindelin for reviewing this patch 
series.
