I don't know whether these things represent an intentional change of libreadline's behavior in Homebrew's build, or a bug, but in either case you should take the issue to the Homebrew support forums. If it's intentional, I imagine there's a way to get the old behavior back. Also, libreadline is fairly configurable, so maybe this boils down to some unintentional change in your ~/.inputrc ? regards, tom lane ————— Thank you very much, Tom. It seems, then, that we have the “microscopic” explanation. I’ll have to to a fair bit of research to find out what to do to fix this problem.
