https://github.com/fricas/fricas/pull/207 ?

My trouble is that I do not know what problem this attempts
to fix.

AFAICS completely disables readline built into GCL, which is
not a big deal due to rlwrap, but some people may wish to
interact directly with gcl command line.

Another trouble is how to test anything: again there are various
GCL snapshots and I do not know which one is in use.

one of the two readlines has to go, either the rlwrap's one, or the
built-in one.
Having them both on leads to some weird interactions, doubling up stuff, etc.

we are talking about GCL 2.7.1 (with a patch it needs, published on
its release page - which is weird, if it doen't build/work without
they should make a new release, but, well...)

If there are two FriCAS disables the GCL one. This setting only
affects cases when there are no rlwrap or when FriCAS was
incorrectly started.

There is one FriCAS, it has to be build with either internal readline,
or rlwrap, but not both.
