In my opinion interactive commands should never raise an error.

Unless of course there is an error - not just a "bad" user behaviour.
The user behaviour might instead throw to a catch label that normally
just continues the command loop (but can be catched too).

We have discussed this before and I have suggested the same thing
then. In my opinion it is important. I guess some people might agree,
but so far no one has had time to:

1) Suggest the policy (oh, yes, I did).
2) Get agreement.
3) Implement.
