machine=`hostname |awk -F. '{print $1}'`
if [ -w / ] ; then

        #remove dot from path
        export PATH=`echo $PATH | sed -e 's/:\.$//g'`
        export PATH
$ '
unset me machine

	username at host:/the/current/path

	root at host:/the/current/path

which is excellently suited for cut/paste when doing
'scp's and such.  Having a two line prompt also means
you can have an entire screen width for your command,
and still see where you are.

But what happens when you ssh to another machine that
doesn't have this alias, or need to sudo to root and
it doesn't have it?  When you log out of that machine,
you need to run a gratuitious 'cd .' to fix your
title bar.

No, for me anything that changes my title bar should be
shot.  One of the reasons I don't use bash[1] since often
it has such an alias.

Besides, I like to label my title bars manually with
'retitle', which is pretty much similar to what you
had but without needing to imbed ctrl chars:
	function retitle {
	        echo '\033]0;'$@'\007\c'

    this thread[2]

[2] This thread being far diverged from perl, so I'm going
    to shut up before Tim starts having stick riddle

   Systems and                to a sufficiently
   Security Engineer          talented fool.
