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 a little 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.
