I did look.  And with some experimentation, I discovered that
the `pwd` works only at the time one does the PS1= and to get 
the bash prompt goodies, one would have to redefine cd  and
do a bunch of tricks ... so I guess I'm still stuck with bash
to get that functionality.  Also,

>host=`hostname -s`
>PS1='->`pwd`
>$host[!]: '

the \n in that string is ignored by ksh and it appears on one
line.  (at least it did for me.)
