Subject: t4017 (diff-retval): replace manual exit code check with test_expect_code
X-Git-Tag: v1.7.4-rc0~65^2~18
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=dd0c69e95638d49f576c3774b8073b68d82ec0ff;p=git.git

t4017 (diff-retval): replace manual exit code check with test_expect_code

This commit takes advantage of Ævar Arnfjörð Bjarmason's recent change
to test_expect_code (test-lib: make test_expect_code a test command) to
simplify several testcases.
