Right.

That's not possible. Vim takes control of a full xterm screen -
either the main screen or the altscreen. When it exits, it leaves a
full screenful of data on whichever of those screens it was drawing
on. It won't ever leave less than one screenful of data. As a
*horrific* hack, you can trick vim into thinking that the screen is
smaller than it really is... I would never actually do this, since I
would be in no way shocked if this breaks horribly somewhere, but...
this does what you want given some very limited testing:
function! HopefullyDontBreakEverything()
" Do nothing if vim is dying from a signal.
if !v:dying
" Remove all other windows
only
" Remove any ~ lines
let &lines = min([ line("$"), &lines])
" Remove the status line
set laststatus=0
" Force vim to redraw the screen
redraw!
endif
endfunction
autocmd VimLeave * call HopefullyDontBreakEverything()
but I really don't think it's a very good idea at all...
