When you try to exit and there is a modified buffer, Vim will try to
show you that modified buffer in the current window, so that you can see
what it is and possibly write it. That's intentional.

Autocommands can always cause things to go wrong. You need to take care
about that when writing them. Especially when using commands such as
":q!".

You do need to use BufWinEnter to do something after the modelines, but
it's also triggered when displaying a buffer in any window. You could
set a b: variable to flag whether it's the first time.
