Subject: [PATCH v2] test: add test for git bisect skip with --term* arguments
Message-ID: <20210421040808.14185-1-bagasdotme@gmail.com>
In-Reply-To: <20210418151459.GC10839@aaberge.net>

Trygve Aaberge reported the current git bisect breakage on [1].
After starting bisection with --term-new and --term-old arguments to git
bisect start, skipping with git bisect skip does not change HEAD as
expected.

Let's add the test to catch this breakage.

Changes from v1:
  * style changes requested by Junio
  * rename test script and edit test description to be more descriptive
  * remove exec </dev/null (I don't know what it means)
  * repo initialization is now on test_expect_success block (as
    requested by Junio)
