Details:

Python has os.devnull which:

> The file path of the null device. For example: '/dev/null' for POSIX, 'nul'
for Windows.

We could have devnull() in Octave too. I would place this in
libinterp/corefcn/file-io.cc next to stdout, stdin, and stderr.  But those
return file handles since they are already open.  For devnull that's not
necessarily true. Any opinions?

I looked into libgnu and they do:


#if (defined _WIN32 || defined __WIN32__) && ! defined __CYGWIN__
  if (strcmp (filename, "/dev/null") == 0)
    filename = "NUL";
#endif
