From fcd43b719b7204fb8859b88fc51f8df6f669bc89 Mon Sep 17 00:00:00 2001
From: Johnny Chen <johnny.chen@apple.com>

Subject: Modified CommandObjectExpression::EvaluateExpression() so that it
 takes an additional (ComandReturnObject *) result parameter (default to NULL)
 and does the right thing in setting the result status.

Also removed used variable ast_context.
