OpenOCD commands w/prefix ocd_ now set the primary Tcl return value instead of messing with ocd_output local variable. Much more straightforward and expected behaviour. The side effect is that the ocd_xxx commands will print output twice(once immediately and once upon completion of command). This is a strange, expected and intentional behaviour.
