Those were just some local changes I had done at some random point when
coming across stuff that I thought could be better. I just sent them now
since my local changes will be lost by me leaving my current job, and
I didn't care enough to push them on a branch somewhere (:

Either these were thought to be good by someone else, or, as it is,
they're not and I'm dropping all three :)
