docs: This utility function contains the logic to determine what streams to use
      by default for standard out/err.
  
      Typically this will just return `sys.stdout`, but it contains additional
      logic for use in IPython on Windows to determine the correct stream to use
      (usually ``IPython.util.io.stdout`` but only if sys.stdout is a TTY).
