Function pane_started 

pub fn pane_started(
    broker: Option<&Broker>,
    connection: &str,
    logged_in: bool,
) -> ConnStatus

A pane’s process on connection started (an SSH pane’s ssh, a durable pane’s attach): one more pane has it open. logged_in says it is a live login already (a durable pane’s helper answered, or nothing better can be known); otherwise it is only connecting, its ssh perhaps waiting at a password prompt, until the shared connection answers (remote::link). A connection already up stays up.
