[9fans] nil, and the danger of zero

[erik quanstrom]

so, as it turns out, not all zeros do the same thing to the stack.....  pfffft.
at least it's a simple reason why venti won't run.

; diffy -c ../boot/local.c
/n/dump/2014/0403/sys/src/nix/boot/local.c:212,218 - ../boot/local.c:212,218
                                f[2] = "tcp!127.1!8000";
                        }
                        configloopback();
-                       run("/boot/venti", "-c", f[0], "-a", f[1], "-h", f[2], 
0);
+                       run("/boot/venti", "-c", f[0], "-a", f[1], "-h", f[2], 
nil);
                        /*
                         * If the announce address is tcp!*!foo, then set
                         * $venti to tcp!127.1!foo instead, which is actually 
dialable.
/n/dump/2014/0403/sys/src/nix/boot/local.c:233,239 - ../boot/local.c:233,239
  
        /* start fossil */
        print("fossil(%s)...", partition);
-       run("/boot/fossil", "-f", partition, "-c", "srv -A fboot", "-c", "srv 
-p fscons", 0);
+       run("/boot/fossil", "-f", partition, "-c", "srv -A fboot", "-c", "srv

        fd = open("#s/fboot", ORDWR);
        if(fd < 0){
                print("open #s/fboot: %r\n");
