The final test in `realpath.in` was based on the no-longer-valid assumption that $PWD cannot be a symlink. Since the recent changes in fish 3.0 to allow `cd`ing into "virtual" directories preserving symlinks as-is, when `make test` was run from a path that contained a symlink component, this test would fail the `pwd-resolved-to-itself` check. As the test is not designed to initialize then cd into an absolute path guaranteed to not be symbolic, so this final check is just wrong.
