Good point. From what I understand, the reason why we need the macro
here is that, when running the test with --root=<path>, the trash dir
might actually be at a path outside `t/`. So the test can't rely on
`./` to read files from `t/`. We don't need the macro for
`test-lib.sh` because the working dir is only changed after it is
sourced (by `test-lib.sh` itself).
