Here's an example raw diff generated by Phabricator:
```
diff --git a/build-steps/generic-build b/build-steps/generic-build

+generic-build.py
\ No newline at end of file
diff --git a/build-steps/generic-build b/build-steps/generic-build.bak
copy from build-steps/generic-build
copy to build-steps/generic-build.bak
diff --git a/build-steps/generic-build.py b/build-steps/generic-build.py
new file mode 100644
```
Applying it with `git apply D0000.diff` I get `error: dev/null: No such file or directory`.
In the diff, I am moving a file, and replacing it's original filename with a symlink to another newly created file.
