Remove this change. I know clang-format probably made it, but it's not part of what you're doing here. If the formatter check fails and it's just this space, we can ignore it.

If you find clang-format making way more changes, you can send a PR to reformat a file, then make changes on top of that. 

This is documented https://llvm.org/docs/Contributing.html#how-to-submit-a-patch.

For tiny stuff like this, we just ask folks to remove the modification and pay less attention to the formatting bot.
