pass a string with embedded quotes, perl hands it off to a shell which results in an extra shell wrapper for every ssh. Well, with SSH_ARGS the way they are, that means we always get the extra shell. While this is a nice optimization it actually matters mostly from linktest_control where I want to make sure that the child that invokes linktest on ops (an ssh) can be killed directly with TERM (say, if user cancels linktest) without worrying about intervening shell screwing with signals, etc.
