    vc._vc: Limit the file information we ask for
    
    We were asking for the full range of standard:: info, but didn't use
    anything except the display name and whether it was a directory. Since
    the standard namespace includes a *lot* of stuff, such as file type
    sniffing, this was very wasteful.
    
    On large version control hierarchies, this is good for a massive speed
    improvement; I've seen up to 400%.
