@shadyvb if I invoke `phpcs-patch` with a commit-span like:

```bash
phpcs-patch --standard=WordPress -r e82920f:31174f73
```

Then I see among the command log:

> == Executing: git show e82920f 31174f73:path/to/file.php

This seems to produce the incorrect results, including a patch followed by the file at the commit `31174f73`, I believe.

So isn't the need to ensure that only the recent-most commit is used for `git-show`?
