As far as I understand, the problem is that GAP does not use the
'history' part of readline, but its own code, to implement 
traditional GAP history behaviour.

However it is now possible to configure readline to have a similar
behaviour than GAP by setting:

"\e[A": history-search-backward
"\e[B": history-search-forward
(and probably similar for Ctrl-r and Ctrl-n).

So it might be possible for GAP to use history while setting this default
to keep the traditional behaviour.

Cheers,
Bill.
