The trick here is to make the cd/chdir command change your prompt whenever
it's invoked.  I dunno about ksh, but SysVR2 sh won't let you and still be
able to retain the same name for the cd command.  The problem lies in the
fact that shell-builtins are searched first, then user-functions, then
$PATH.  This means there's no way to intercept-and-redefine the cd command.
Csh will let you because aliases are expanded before shell-builtins and path.  

It is possible, however, if you call your cd command something other than
'cd'.  This command would call cd to change your directory and then set
your prompt to the new directory.
