Merge branch 'mr/bisect-in-c-4'
Rewrite of "git bisect" in C continues. * mr/bisect-in-c-4: bisect--helper: retire `--bisect-next-check` subcommand bisect--helper: reimplement `bisect_run` shell function in C bisect--helper: reimplement `bisect_visualize()` shell function in C run-command: make `exists_in_PATH()` non-static t6030-bisect-porcelain: add test for bisect visualize t6030-bisect-porcelain: add tests to control bisect run exit cases
