remove empty file with space in file name

This file is empty, and worse it contains a space in the name which messes up find commands running over all files in the repository. From what I can tell it has come straight from SVN years ago and not been touched since. So hopefully just removing this file is fine, and doesn't cause other things to break that depend on its mere existence.

I don't actually know why this file is there in the first place or who to ask about that. So this MR is my way of asking. The main reason I want to see it gone is that files with spaces in the name don't work well with doing things like:

find * -type f | xargs grep ...

And this is the only file with a space in the name in the repository.

If this file is still needed, just close this.
