Subject: t5500: Modernize test style
X-Git-Tag: v1.6.4-rc0~115
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=3902985a58d5b5f42406f11f1c8b9b87a98c7e3c;p=git.git

t5500: Modernize test style

Code outside of the test harness was emitting "Initializing..." from
git-init. Fixup this test to be more modern:

    - test_expect_object_count() and count_objects() are unused

    - use grep directly instead of test "..." = $(grep ...)

    - end the test_expect_success line with a single-quote and put the
      test on a new line

    - put as much code inside the test harness as possible

    - no_strict_count_check is unused and duplicates the test
      "new object count"

    - use && whenever possible to catch errors early

    - use test_tick instead of GIT_AUTHOR_DATE=$sec

    - remove debugging aid log.txt

    - use subshells instead of cd-ing around

Also merge the pull test into one large test.
