>Description:
	Pax tests are failing with:
	cd: Unable to determine new working directory

>How-To-Repeat:
	[12:43pm] 42>mkdir -p foo/bar
	[12:43pm] 43>chmod 111 foo
	[12:43pm] 44>sh -c '{ cd foo/bar; }'
>Fix:
	Don't complain when changing directory if you can't determine
	the current working directory?
