I think it should be the default for completion to work.  What isn't 
clear to me is if we need an option (nocomplete?) to disable it, and if 
there should be a way to hide individual labels from view.

I would appreciate user comments on the above.  Otherwise I'm probably 
going to accept the patch with the sense reversed (a nocomplete option.)
