Re: rrd_graph and flush behavior

Actually, the following code does the same using less code:

   if (*path == '/') /* absolute path */
   {
     if (! is_unix)
     {
       rrd_set_error ("absolute path names not allowed when talking "
           "to a remote daemon");
       return (NULL);
     }
   }
   if (is_unix)
   {
     realpath (path, resolved_path);
     ret = resolved_path;
   }

Basically, we want realpath() to be called every time we have a unix  
socket, it doesn't matter if it's a relative or absolute path.
