Correctly print the unknown command name

Browse source 
by now, if someone calls: `program --validflag unknowncommand` the
output will be:

```
Error: unknown command "--validflag"
Run 'program help' for usage.
```

This patch strips out flags so the unknown command is printed:

```
Error: unknown command "unknowncommand"
Run 'program help' for usage.
```
