Given the following script:

--------------
while true
do
	break
	echo "Still in while"
shift
done
echo "Out of while"
-------------

When run by bash the following output is produced:

	Still in while
	Out of while

When run by bin/sh the following is produced:

	Out of while

It appears the break command just sets a flag, which is only checked
each time the while condition is checked. Then every command in the
do--done part is executed.
