PS1 change (ksh)

[BALDWIN]

If you want the cwd in the prompt, just make a new function called, say, ch:

ch()
{
	if cd $1
	then PS1="[`pwd`] "
	fi
}

This will work in SVR2 sh as well as ksh.  I see no reason why the shell
has to be modified at all.  We don't need to add any extra baggage to the
shell.  For instance, why is there $PWD in ksh and $cwd in csh?  Doesn't
`pwd` do the same without adding another funny variable to the shell?
