You are correct, here is no problem in bash-4.0 alpha. My apologies.

An error message when bind is used and line editing is not enabled would
help.

Alas, I suspect many will not try to use bind but still use "read" or
perhaps a set +o emacs and subsequently expecting some of default key
bindings which no longer are in effect. I threw in the bind command just to
try to help me see what was going on.
