Post the shell function.  Mine took eleven lines and two minutes (without
any option parsing).

cd()
{
        builtin cd "$@" && return || es=$?
        if [ -f "$1" ]; then
                case $1 in
                */*)    ;;
                *)      return $es ;;
                esac
                newdir=${1%/*}
                builtin cd "$newdir" && echo $newdir
        else
                return $es
        fi
}
