```
server.settings.Server.set_hook(self, name: &str, command: impl Into<OsString>) -> Result<(), Error>
```

Set one global hook.

Hooks live in the option tables, so [`Server::get_global_option`] reads
one back under an indexed name such as `after-new-window[0]`.

# Errors

Returns an error when tmux rejects the hook name or command.
