[v5,1/5] t6030: modernize "git bisect run" tests

Commit Message

Aaron Lipman Aug. 7, 2020, 9:58 p.m. UTC

Enforce consistent styling for tests on "git bisect run":
- Use "write_script" to abstract away platform-specific details.
- Favor current whitespace conventions.
- While at it, change "introduced" to "added" in the comments to make
  them read better.
