	With version 1.03 I get the prompt correct immediately. But (spoiler)
	when cd'ing, pushd'ing, popd'ing I get the value of one of two
	shell variables. If I go to a sub-directory I get (on screen) the value of
	one variable. On dc'ing back (or popd'ing) I get the value of another - and
	I can do nothing but hit return (example):
	
	  	 tnds01:~ (24) cd /usr/local/src/patch
	  	 SHLVL=2
	  	 tnds01:/usr/local/src/patch (25) cd ..
	  	 tnds01:/usr/local/src (26) cd ~/src/c
	  	 tnds01:~/src/c (27) cd ~/
	  	 PAGER=/usr/local/bin/less
	  	 tnds01:~ (28)

I have sent a fix for this to Brian.
