Subject: [PATCH] check that we have enough arguments

```
panic: runtime error: index out of range

goroutine 1 [running]:
panic(0xbb8de0, 0xc82000e080)
        /usr/local/go/src/runtime/panic.go:464 +0x3e6
main.main()
        /go/src/github.com/tendermint/tendermint/cmd/tendermint/main.go:48 +0x811
```
