rev-parse test: use test_cmp instead of "test" builtin
Use test_cmp instead of passing two command substitutions to the "test" builtin. This way: - when tests fail, they can print a helpful diff if run with "--verbose" - the argument order "test_cmp expect actual" feels natural, unlike test <known> = <unknown> that seems backwards - the exit status from invoking git is checked, so if rev-parse starts segfaulting then the test will notice and fail Use a custom function for this instead of test_cmp_rev to emphasize that we are testing the output from "git rev-parse" with certain arguments, not checking that the revisions are equal in abstract.
