```
Server.join(_:into:direction:size:)(pane: Pane, into: Window, direction: PaneDirection, size: PaneSize?) -> ()
```

Moves a pane into another window, splitting it.

A split that moves a pane rather than starting one, so it says where the
pane goes the same way ``Server/splitWindow(_:direction:size:startDirectory:)``
does — and defaults the same way, to ``PaneDirection/below``.

## Raises

- `TmuxError`
