How do I make vim display virtual space at the bottom when opening a file?

Question

I really like not having my cursor at the bottom part of the screen. Using :set scrolloff=20 does help when scrolling down a file, but it doesn't work when I reach the bottom (unless I zz).

Another problem (and the main question) is how to get vim to show the virtual space when opening a file? I have it setup to set the cursor at the last line where I was editing, and if that line is at the end of the file, it will open at the bottom.

Answer 1

Perhaps

au BufWinEnter * exe "normal zz"

But I guess there will be side effects. Test thoroughly.

One side effect: Assume you have 2 buffers loaded and Vim has only one ("full terminal") window. So one buffer is displayed. The other is hidden. If you switch to the hidden buffer, zz will be executed.
