This will allow for more semantic code in h/menu, menu bar, and other places when handling buffers with hyperdrive-current-entry where the entry doesn't exist in the hyperdrive (because it's not been saved yet or it's been deleted).
We intend to add an
existspkey to thehyperdrive-entryetcslot, which will be one oft,nil, or'unknown.With the upcoming integration with the new ~/$/history~ API endpoint, this change is likely not necessary.
