Title: Fix tegh error on empty command.

Presently, if you just enter on at the tegh prompt, or just give a few spaces, you get an error:

```
>
Error: '' is not a valid command.
Try typing 'help' for more info.
```

I enter blank lines regularly and this behavior quickly gets irritating.

This patch just makes tegh ignore empty commands.
