In current Tramp 2.5.0.4, this has been mitigated by wrapping the
insert-file-contents-literally call in tramp-sh-handle-make-process with
ignore-errors.

However, handling stderr buffers in Tramp's make-process is still a
mess. So I've started to reimplement this, using a named pipe on the
remote machine. make-pipe-process, the natural choice, does not work for
remote processes.

Best regards, Michael.
