As I see it, this is a readline issue.  It is really outside the scope
of the Octave project.  If there is a simple way to make this
configurable in readline, then find out what that is and show what
change a user can make to her ~/.inputrc file to change the behavior.
But I don't see anything to fix in Octave itself, and I would guess
that most of us here are not readline experts, so we are probably the
wrong people to be asking to fix that library.
