Ash Brad explained, it can't be an external program, 
and therefore it never was.

You can build shell-*internal* aliases and functions that maybe
change the prompt and then call the original, but you can't have
useful cd as an external program because that would (in the Unix-like
world) execute in a new process, resulting in all changes to the
process being lost when it exits.
