>Organization:
Not much
>Environment:
System: NetBSD 5.99.7  i386
>Description:
	According to SUSv3 <http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html>,
	the shell should expand the value of PS1 before printing it
	on every prompt.  NetBSD's /bin/sh does not do that.
>How-To-Repeat:
	It actually does this:

	$ ( cd /tmp ; ENV='' /bin/sh -i )
	$ PS1='${PWD} $ '
	${PWD} $ 

	It should do this instead:

	$ ( cd /tmp ; ENV='' /bin/sh -i )
	$ PS1='${PWD} $ '
	/tmp $ 

>Fix:
	Expand PS1 when printing the prompt.
