Details:

(Not sure if this can be considered a bug, or just a change in the
functionality from older versions, but just in case.)

Pressing up-arrow will show past commands. But executing this script:

#!/usr/bin/octave -q

a = input(">> ", "s");

it will prompt for an input, but when pressing up-arrow it will show ^[[A.
This is for version 4.0.0, but in older versions, like 3.2.4, up-arrow would
work fine in the executable script, showing the commands in the history file,
just as the original prompt in the GNU Octave command window. I've checked and
both runs (command window and script) are updating the same history file, so
may be the thing is in the way input is taken. I believe it's a readline
thing, but can't figure out how to make it work.
