Another workaround would be to use the bundled readline, as in

The above patch needs to be modified of course to preserve the working
setup for RELENG_5 etc, but I don't know how to do that.

The bash port is not broken, so another thing would be to
deinstall bash2 and use bash instead. (Why do I always discover things
like this right after I submit a PR.)
