:previous_same_depth and :next_same_depth internals

This can be tested with

```
[[verbs]]
invocation = "psd"
key = "ctrl-up"
internal = ":previous_same_depth"

[[verbs]]
invocation = "nsd"
key = "ctrl-down"
internal = ":next_same_depth"
```

I'm not sure it's really useful but it's costless and allows
experimentations.
