Houch... this is going to hit everywhere, especially for wcmd. At this point I even start to wonder if some heuristics trying to identify filenames would not be a "good" idea (in a "less bad than all the others" way). Although even something as simple as only quoting when it seems needed because of e.g. space in the arg might help a lot.
