This is supposed to be combined with the preceeding code to a single
expression in the end, right? I don't quite understand why writing
to STD_ERROR_HANDLE doesn't work. Is STD_ERROR_HANDLE not connected
to the ConPty?

For a quick test if the process is connected to a pty, you can
use `if (istty_slave_dev (myself->ctty))'
