popd +1 will remove the first entry in the directory stack (given current
directory is the 0th entry) so if you have a stack that was
	"/ /mnt/etc"
popd +1 will leave it as "/" and since this does not involve changing
directory it doesn't matter that /mnt/etc no longer exists. (This works on
all machines I have access to, Pyramid, Sun, 4.3BSD Vaxen).
