Re: Persistent undo and force quit

Here's a first draft of getting it to work:

"save undo if we qa!

function! MyWundoQuit()

    silent! later 99999

    earlier 1f

    let undof = escape(undofile(expand('%')),'% ')

    exec "wundo " . undof

endfunction

autocmd BufWinLeave * call MyWundoQuit()

I don't see a way to undo back to when the file was written last other than going later, and then earlier 1f.  That doesn't work in the case that the file hasn't been changed at all, so it's not ideal.  But, it seems to work in practice pretty well.
