Using 'test_must_be_empty' is shorter and more idiomatic than >empty && test_cmp empty out as it saves the creation of an empty file. Furthermore, sometimes the expected empty file doesn't have such a descriptive name like 'empty', and its creation is far away from the place where it's finally used for comparison (e.g. in 't7600-merge.sh', where two expected empty files are created in the 'setup' test, but are used only about 500 lines later). These cases were found by instrumenting 'test_cmp' to error out the test script when it's used to compare empty files, and then converted manually. Note that even after this patch there still remain a lot of cases where we use 'test_cmp' to check empty files: - Sometimes the expected output is not hard-coded in the test, but 'test_cmp' is used to ensure that two similar git commands produce the same output, and that output happens to be empty, e.g. the test 'submodule update --merge - ignores --merge for new submodules' in 't7406-submodule-update.sh'. - Repetitive common tasks, including preparing the expected results and running 'test_cmp', are often extracted into a helper function, and some of this helper's callsites expect no output. - For the same reason as above, the whole 'test_expect_success' block is within a helper function, e.g. in 't3070-wildmatch.sh'. - Or 'test_cmp' is invoked in a loop, e.g. the test 'cvs update (-p)' in 't9400-git-cvsserver-server.sh'.
