Remove trailing spaces using vim

This little function will remove trailing space and maintain your position in a file. I started with something like this.

    " Removes trailing spaces
    function! TrimWhiteSpace()
        %s/+$//e
    endfunction

I found that it left me at the bottom of my file, and I kept forgetting to mark my position before running it. After a little research I found this solution, it saves your positon and returns it to you after it's done.
