In Fai, that's not a feature, it's a bug.  Completion in cmd.Cmd is 
screwy when it comes to hyphens, so I have to add prefixes, find 
completions, then chop 'em off.  But I can see how that's be a nice 
thing to do on purpose.

Well, the only place I can see order mattering is with positional 
parameters.  For options, the completion type is always "strings from 
this list", and for option arguments, it's unambiguous.
