Many scripts compare actual and expected output using "diff -u". This is nicer than "cmp" because the output shows how the two differ. However, not all versions of diff understand -u, leading to unnecessary test failure. This adds a test_cmp function to the test scripts and switches all "diff -u" invocations to use it. The function uses the contents of "$GIT_TEST_CMP" to compare its arguments; the default is "diff -u". On systems with a less-capable diff, you can do: GIT_TEST_CMP=cmp make test Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
