SupportsItem () being applied to ModifierItems children

[Stephen Elson]

If modifier items have children which can be expanded (e.g. directories), the children are filtered by SupportsItem () rather than SupportsModifierItemForItems ().

For example, here the items are directories or files not within /foo, and modifier items are directories within /foo. However, expanding the modifier items is not possible as their children are filtered by SupportsItem.

public override bool SupportsItem (Item item)
{
 string path = GetPath (item);

 return !path.StartsWith ("/foo");
}

public override bool SupportsModifierItemForItems (IEnumerable<Item> items, Item modItem)
{
 string path = GetPath (modItem);

 return Directory.Exists (path) && path.StartsWith ("/foo");
}
