trailing white space

@onlytailei can you avoid introducing trailing white spaces? Currently newline definitely introduce trailing white space, among other cases.

Your editor should support that function, usually. If you are using vim then %s/\s\+\$//g will do. Otherwise, IDLE have that capability as well.

No problem. My vimrc file has this highlight before. I will configure it on my laptop.
