This is the termination sequence for bracketed paste mode, which is
enabled by default in readline-8.1:

rlprivate.h:#define BRACK_PASTE_INIT    "\033[?2004h"
rlprivate.h:#define BRACK_PASTE_FINI    "\033[?2004l\r"


You can either require the user to disable it, disable it from inside
octave:

rl_variable_bind ("enable-bracketed-paste", "off");

or set the terminal to "dumb"

rl_terminal_name = "dumb";

in which case it's turned off.
