If Octave is compiled to use readline, it should pay attention to
whatever size readline thinks the terminal is.  That's maintained in
the screenwidth variable in readline, and it is set in
_rl_get_screen_size in terminal.c.  Exactly how it is set depends on
the system and terminal you are using.  On mine, it is set to the same
value I set using `stty columns NNN'.  On others, it may be set from
information stored in either the termcap or terminfo file, or the
COLUMNS environment variable, or, if all else fails, it defaults to
80.
