Hack for Windows so that if (1) the exit status is nonzero and (2) we think we have our own DOS box (i.e. we're not started from a command line shell), we print a message and wait for the user to hit a key before the DOS box is closed. The hacky heuristic for determining whether we have our *own* DOS box (due to Mark Hammond) is to test whether we're on line zero...
