The '-D' option for the 'am' command appears to be optional, so reflect that in the usage.

    private void showUsage() {

        System.err.println("usage: am [start|broadcast|instrument|profile]");

        System.err.println("       am start -D INTENT");

        System.err.println("       am start [-D] INTENT");

        System.err.println("       am broadcast INTENT");

        System.err.println("       am instrument [-r] [-e <ARG_NAME> <ARG_VALUE>] [-p <PROF_FILE>]");

        System.err.println("                [-w] <COMPONENT> ");
