```
Server.unsetOption(_:scope:)(name: String, scope: OptionScope) -> TmuxReply
```

Puts an option back the way it was before anyone set it.

What that means depends on the option. A user option — `@`-prefixed,
which tmux never interprets — is deleted outright and stops being
listed. One of tmux's own reverts to its built-in default, so it is
still listed, carrying a value nobody chose.

Unsetting a name nothing was set to succeeds and changes nothing.

## Raises

- `TmuxError`
