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

Set one hook to a tmux command.

Hooks live in the same option tables, so a hook is an array option and
[`Self::typed_option`] reads it under an indexed name such as
`after-new-window[0]`.

# Errors

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

Returns [`crate::Error::OptionScopeMismatch`] when tmux keeps the
option in another of its tables.
