No I didn't find that! This is exaclty what I was looking for :-) I knew
there had to be something better then writing this myself.

I just had some trouble wiring it up, but it now finally works. For
reference, what I did was to add this code to the openSSH method:

    def openShell(self, protocol):
        serverProtocol = ServerProtocol(MyRecvLine, self)

And MyRecvLine is a subclass of HistoricRecvLine.

Yeah definitively, documentation is sorely needed. For this I already
bought the upcoming Twisted book. I hope that this will give me some
more insight why I have to do some of the things the way they are.
Unfortunately I am not sure if I am the right one for documentation
since I still struggle with some of the concepts. But I would like to
publish this combined sftp and command server as a reference.
