Yes, I know.  That old thread says that, and it was the reason the
upgrade never happened back then.

Does it make sense to upgrade to 6.3 when 7.0 is already in beta?  We
do want eventually start using a newer Readline, I hope.  If so, we
need to start fixing the problems the update causes, otherwise we will
be left behind.  Either our tests need to be amended or Readline 7.0 is
not a simple drop-in replacement, and more of our code needs to be
changed.

But I don't think it makes sense to do nothing, or start using an old
version of Readline.  We will be just deferring the problem for later,
and it won't fix itself, I think.

Thanks.
