Shar has been cleverly designed to throw away stderr
directly to /dev/null.  So, it detects the problem but
you don't get to see it:

  if (output == NULL)
    output = stdout;
  if (isatty (fileno (output)) && isatty (STDERR_FILENO))
    freopen ("/dev/null", fwriteonly_mode, stderr);

This is so that error messages are not mixed in with the
desired output.  A better choice could be made, like deferring
error messages then prefixing the error output with shell
comment markers.  I'd accept such a patch.
