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

Set one global session option to text, unchecked.

Sessions inherit from this table, so it is where a default belongs.
[`Self::set_typed_global_option`] checks the value first.

# Errors

Returns an error when tmux rejects the name or value.
