Add an Iterator

[Yamakaky]

We could do:

for cmd in editor {
    match ...
}

It would end on EOF or

And for ?

In my code, I ignore it. It's handy if you want to discard the current line. python does it.

Something like:

impl<C: Completer> Iterator for Editor<C> {
    type Item = Result<String>;

    fn next(&mut self) -> Option<Result<String>> {
        let readline = self.readline(""); // FIXME prompt
        match readline {
            l @ Ok(_) => Some(l),
            Err(error::ReadlineError::Eof) => None,
            e @ Err(_) => Some(e),
        }
    }
}

?

Yeah, something like that. The prompt could be configured at creation time, since it tend to stay the same for most program. You should also keep the current interface, in case someone want to do something different

SGTM. Just add an implementation for IntoIterator for extra convenience ^^
