Taking a quick look at DiffOrig, then switching back

Question

I've discovered this great command from the documentation:

 command DiffOrig vert new | set bt=nofile | r # | 0d_ | diffthis
    \ | wincmd p | diffthis

So I've come up with this:

command DiffOrig vert new | set bt=nofile | r # | 0d_ | diffthis | wincmd p | diffthis | wincmd p
map <Leader>do :DiffOrig<cr>
map <leader>dc :q<cr>:diffoff!<cr>

The problem is, when I se \dc, it will jump back to the beginning of the file, not where I left it prior to issuing \do. How to fix this?

Please try this yourself, see what the problems are and how to fix them. And tell me how to fix them too :-)

You could try:

command DiffOrig let g:diffline = line('.') | vert new | set bt=nofile | r # | 0d_ | diffthis | :exe "norm! ".g:diffline."G" | wincmd p | diffthis | wincmd p
nnoremap <Leader>do :DiffOrig<cr>
nnoremap <leader>dc :q<cr>:diffoff<cr>:exe "norm! ".g:diffline."G"<cr>
