The changes in com.sun.tools.javac.main.Option don't appear strictly necessary for the start of release updates...

test/langtools/tools/javac/options/HelpOutputColumnWidthTest.java line 50:

> 48: public class HelpOutputColumnWidthTest extends TestRunner {
> 49: 
> 50:     public static final int MAX_COLUMNS = 80;

I though that the default terminal width was 24x80 in most systems, so 84 seems an odd choice.  I agree that 80 seems more appropriate.
