Details:

The "input()" function returns an empty result when nargout = 0.

This was originally reported on the help list.

The patch below works for me, but I'm not sure if this is a proper fix.

   int nargin = args.length ();
 
   if (nargin == 1 || nargin == 2)
-    retval = get_user_input (args, nargout);
+    retval = get_user_input (args, 1);
   else
     print_usage ();


Should "get_user_input ()" be modified to always return at least one arg?
