[TxMt] includes in completions and exclusive completions

[Max Williams]

Thanks, Allan, my first point was actually the one I wasn't too  
bothered about. blocking scopes was my main objective in that request.
so I'm very happy that you agree  :).

On a similar note, would it be possible to have a bunch of  
completions for a scope
but not for its contained elements.
eg:
scope=
foo, !foo bar

I think I remember someone talking about this but can't remember the  
result.

regards,
Max
