Nit: this could be 't6030: modernize "git bisect run" tests' to tighten
the area a bit and to begin with a verb.

Missing sign-off.

I think this should come earlier in the series, probably already as
patch 1/4. Some reasons for that:

 * If this effort doesn't go any further (let's hope it does!), at
   least the initial cleanup can be merged, so that later endeavours can
   find a slightly cleaner table to start with.

 * Revisiting your other patches in `git log` after they've been merged,
   it will be obvious that they follow other tests, so one can focus on
   what they do and not on how they differ.

 * Let's first tidy up, then build shiny new things. ;-)

All of these look like correct, worthwhile modifications. The
s/introduced/added/ changes aren't mentioned in the proposed log
message. They have been discussed up-thread, but it might still be
good to add something like

  While at it, change "introduced" to "added" in the comments to make
  them read better.

FWIW, I guess there's some minor added value in doing that change and
since you're doing other changes anyway, it might actually be worth the
churn.

You change two tests like this, but there are other "git bisect run"
tests that look like they're in need of some modernizing. Looking for
"chmod" I spotted the ones I'm tweaking below. Looking for "git bisect
run" you might find more that may contain some funny indentation. I'll
leave it to you where to stop going down that rabbit-hole but if you do
re-roll, it might make sense to squash in the diff below, maybe with
some modifications to the commit message. (Signed-off-by: Martin Ågren
<martin.agren@gmail.com>, FWIW.)
