lisp/term/ns-win.el modification

[Jean-Christophe Helary]

I've noticed that the system service provided by NS-Emacs (and Aquamacs) did 
not allow multiple strings to be selected for opening them in emacs since the 
function called (dnd-open-file) accepts only one argument.

A few days ago I've written a patch to the aquamacs/ns-win.el that was accepted 
today by David.

Since the issue exists also in NS-Emacs I was wondering what could be done to 
have the patch (or an adaptation) applied to the original lisp/term/ns-win.el 
file.
