I cannot reproduce this here, FWIW.  I get the expected behavior
without any "buffer interaction".  But I'm not using the GTK+ build of
Emacs, and I did need to modify the recipe to use a remote directory I
can actually access (instead of "/scpx:bangmyhead <at> 192.168.0.46:"), and
used start-file-process-shell-command to avoid the need to specify the
shell's file name explicitly.  Here's the recipe I tested:

  (let ((shell-cmd "ls -la")
	(output-buffer "my-buf")
	(default-directory <REDACTED>)
	(process-name "my-proc"))
    (start-file-process-shell-command
     process-name
     (get-buffer-create output-buffer)
     shell-cmd)
    (switch-to-buffer output-buffer)
    (with-current-buffer output-buffer
      (goto-char (point-min))
      (find-file-other-window "ooo")))

With the above recipe, I see the end of the listing (which is longer
than the window in my case).  This is what I'd expect.

Can someone who uses the GTK build of the master branch reproduce the
problematic behavior?
