 When I type "port ex" and press tab twice, it explains that I could mean
 "exit" or "extract". While technically that's true, there's no reason why
 anyone would ever want to type "port exit" so I suggest that "exit" be
 removed as a possible completion. That would allow me to type "port ex"
 and tab to get "port extract" which is what I wanted.
