SIGSEGV if running encoder without parameters.

[xcrh]

Troublesome code is in pack.c, line 936

  if (argc<3) {
    printf("usage: lzoma input output [lzlit lit olz len dist]\n");
    int i;
    int total=atoi(argv[1]);//16*1024*1024; <- here it going to crash.

Crash happens because if you run program without any params at all, only argv[0] is available (proram name) but you're trying to access argv[1], which may or may not exist.
