Since eight-space indentation violates the Java coding conventions it doesn't 
deserve consideration.  Code that indents eight spaces should be rejected in 
code review and brought into compliance.

<http://www.oracle.com/technetwork/java/codeconventions-136091.html#262>

But your larger point is valid, and you can just do this:

   for( ...some code )
   {
      do some init
      do a little work
      declare a temporary variable
      declare another temporary variable
      declare yet another temporary variable
      declare still yet another temporary variable
      declare a temporary variable inside
   }

The reason to go with the supposedly "extra" braces is to guarantee that a 
temporary variable is not re-used, but if a method is so long that that's a 
risk there's a good chance that it's too long.

And again I say, "anonymous block" makes no sense because blocks aren't named 
in the first place.
