why adding whitespace here?

I had some test code here. It's a good practice as far as I am concerned to have whitespace on blank lines between code anyway, so I kept it.

git complains about trailing whitespace of any sort, so I prefer to never have trailing whitespace if at all possible. All of the editors I use nowadays are smart enough that they will indent correctly without having to leave whitespace on empty lines like this.

I add the whitespace because it makes it much easier to copy-and-paste to those blank lines, especially when I include a newline in my copied code.

Whatever the case, I'll remove it -- I don't have strong feelings either way and see no reason to fight about inconsequential whitespace. Braces, however, are a different story... 😉
