Formatting of River Source Tree

[Gregg Wonderly]

As I've said here before and elsewhere, I really feel that tabs only is the most 
beneficial indentation to use.  The reason is that it allows people who use odd 
tab intervals to still see things and use their tab key while editing without 
having to change their IDE settings while editing.

Sun has an old formatting document that discusses using spaces only, and 
netbeans does this by default.  The biggest issue for me, of course, is that I 
use 4 character tab expansion and tabs only in all of my development.

In an open source world, all tabs is really the only thing that provides the 
most flexibility it seems to me.
