Problems with command-line options silently ignored

In this case, the **rpcport** argument is silently ignored:

```
-testnet -nolisten -server -connect 192.168.1.11 -rpcport=12345
```

However, when adding a = after connect, it works, i.e.

```
-testnet -nolisten -server -connect=192.168.1.11 -rpcport=12345
```

It could be that the first is simply wrong; in that case, it should probably show an error message.
