The extra ^D\b\b are the EOF character being echoed. These EOF
characters are being generated by the new script(1) to pass through the
EOF condition on stdin.
One fix would be to change the termios settings temporarily to disable
the echoing but this may cause problems if the application is changing
termios settings concurrently and generally feels bad.
It may be best to remove writing EOF characters, perhaps adding an
option to enable it again if there is a concrete use case for it.
