The last time this came up, I wrote:

        This is the behavior that Posix requires:  when CDPATH is used,
        bash outputs the name of the new working directory to stdout.
        Commands and shell functions need to take this into account.

There is no such thing as `bourne mode'.

Both of these fail the posix conformance test.
