    file: Change string of unreadable directory item count
    
    We are displaying "? items" in the size column for unreadable folders.
    
    This string is weird and doesn't contribute a clear meaning, but a long
    string such as "uknown number of items" is not desirable either.
    
    So, change this string to "--", matching what is used when item count
    is disabled.
