Not really I guess.  I don't know how to set EDITOR correctly to do the
following:

   - M-x shell
   - ssh remote-server
   - su -l
   - vipw  --> open a new buffer in *this* Emacs

But, I could do this with with-editor and eshell (maybe it could work
for M-x shell also, I don't know) as follow:

   - C-x C-f /ssh:remote-server|su::
   - M-x eshell
   - vipw  --> and here it works, opening an Emacs buffer through
               emacsclient so I could edit and C-c C-c when done

I am not an expert of with-editor but it is one that it does well.
