Begin work on Issue 76

1) Use two print statements to keep it simple
2) Put the "If no user is specified" above the previous statement
3) Keep the default [ec2-user] for those old unix cronies like myself that
expect that behavior (even though it's duplicate to your sentence).
Modified (default) user entry according to Glen's suggestions.
