        is there a way to tell bash *not* to change the termios setting
        when using read -d when the fd is a terminal?

        I tried

        read -u0 -d x var # as in zsh's read -u0 -k 10
        read -u4 -d x var 4<&0

        to no avail.

        I think it's not that much of a useful feature given that it
        can be implemented more nicely (i.e. the user can still use
        backspace, <Ctrl-W>...) with "stty eol" and standard read or dd,
        so it would be nice to be able to disable it.

        I'm not saying "read -d" is not useful, just that one may not
        want the extra undocumented behavior for terminal fds.

Best regards,
