Yeah, I've stumbled over this, too, but didn't have the time to work
on it. And what's even more irritating, for me it shows that `file' in 
the list but doesn't complete to it.

Right, I hadn't thought about that. (The style was (and still is) very 
experimental, it was added in only one or two minutes, without
thinking much about the consequences -- and I always thought I was the 
only one using it ;-)

Or the word before the command (in _precommand).

But only when we've got it working better...
