    Bug 677974 - GIMP suggests XCF as default export format
    
    Only auto-add .xcf if it's a save (not an export) dialog, instead do
    not auto-add anything and ask the user to enter an extension, that's
    less mysterious than saving in the last-exported format which the user
    maybe doesn't remember or want.
