wait, this patch file was produced with git diff > blah.patch in the other repo.
If that pattern doesn't work with Bazel it seems like a big problem? I think it's bazel that should be fixed to work with Git-produced diffs maybe?

[meteorcloudy]

Thanks, indeed, I tested with diff on adding/deleting one liner file. It does output such format, I'll fix this from Bazel side.
