reload() doesn't really need to know the old path
Just whether it's safe for it to keep an anchor on the current item. I've left in the safety check for an empty entries array, for the theoretical case of an empty or entirely filtered-out root directory. It will likely crash in that case, anyway, the cursor may be either -1 or 0.
