Add a way to retrieve the current completer about rustyline HOT 2 CLOSED

Hello,
You can keep ownership of your Completer by passing a reference:

    let c = FilenameCompleter::new();
    let mut rl = Editor::with_config(config);
    rl.set_completer(Some(&c));
    // then do something with c

Tell us if it is good enough.

Oooh, I didn't think of that. Unfortunately, while I can keep the ownership of the completer, I cannot modify it, because it would require having a immutable reference and a mutable reference to the completer at the same time (it's the same if I have a mutable owned completer and an immutable reference to it).
