I think the key distinction here is between "need to input" and "need to 
see". As long as the user doesn't need to input the directory, I think 
it's fine if they end up seeing it at some point.

This sounds like it'll filter out all results if the user *does* input 
the directory, in all or at least some of the cases.

Please think back to the examples I gave in the other thread.

Having it customizable would be ideal, but I'm not sure it's possible to 
have uniquify-style completions without excluding some valid usage 
scenarios, like mentioned above.
