Documentation

Ask before exiting Emacs if it has other live clients.

A "live client" is a client with at least one live buffer associated with it. These clients were (probably) started by external processes that are waiting for some buffers to be edited. If there are any other clients, we don't want to fail their waiting processes, so ask the user to be sure.
