FTR, the implementation in Tramp is different from what is described
here. And honestly, I even don't know, how to implement these two
processes for the remote case.
The current implementation in Tramp redirects stderr to a temporary
file, if it is separate from stdout. This temprary file is associated
with the :stderr buffer, and it runs auto-revert-mode. Maybe not very
elegant, but working so far.
I don't know whether we shall document this different behavior, or
whether we shall find an implementation in Tramp for what is
described. For the latter, I would need help, as said. Or at least ideas.
Best regards, Michael.
