CORE-11857 CORE-13736 It will be followed with a separate fix for the FOR-loop code. Fixes some cmd_winetests. A NULL pointer can be returned for a valid existing batch/FOR variable, in which case the enhanced-variable getter should return an empty string. This situation can happen e.g. when forcing a FOR-loop to tokenize a text line with not enough tokens in it.
