You can always use something like
	$(shortpath "$PWD")
in you PS1 prompt to generate a shortened path.  Here is a sample
shorpath function:

function shortpath # $1 [len]
{
	typeset path=$1
	integer len=${2:-20}
	(( len < 5  && len=5 ))
	[[ $path == "$HOME/"* ]] && path='~'${path#${HOME%/}}
	if	(( ${#path} < len))
	then	print -r -- "$path"
	else	print -r "...${path:4-len}"
	fi
}
