Though it might be a little less surprising if all places that print
the exit code print it the same way.  That way it's possible that
frontends just treat the exit code as a string, and present it as
is to the user.  They may already be doing that.

The =thread-group-exited code has:

mi_inferior_exit (struct inferior *inf)
{
  struct mi_interp *mi = top_level_interpreter_data ();

  target_terminal_ours ();
  if (inf->has_exit_code)
    fprintf_unfiltered (mi->event_channel,
			"thread-group-exited,id=\"i%d\",exit-code=\"%s\"",
			inf->num, int_string (inf->exit_code, 8, 0, 0, 1));

(I bet that's where the new code was copied from.)
