From 5ac84a37935d8e1c62484032259d09f5ac95c0e7 Mon Sep 17 00:00:00 2001
From: Justin Clark-Casey (justincc)
Date: Wed, 30 Jan 2013 03:44:56 +0000
Subject: Fix issue where lsl -> c# generation in co-operative termination mode
did not correctly handle single statement versions of for, while and do-while
loops.
Add regression tests to validate the fix.
This problem will not affect the default abort termination mode.
