There's really no need to add this to the /bin/sh source.  Just put
the following (or similar) into .shrc.  Or, use bash.  One caveat: the
"command" builtin of /bin/sh is currently broken, so this will only
work on /bin/ksh at the moment.

# Print the working directory, etc. in the prompt

cd_prompt () {
    command cd "$@"
    export PWD
    case $PWD in
	$HOME*) PS1="${_host_short}:~${PWD##${HOME}}" ;;
	*)      PS1="${_host_short}:$PWD" ;;
    case $TERM in 
	echo -n "]2;${PS1}]1;${PS1}" ;;
    case ${_user} in
	root) PS1="${PS1}# " ;;
	*)    PS1="${PS1}\$ " ;;

alias cd='cd_prompt'
