In *emerge-setup* above is this code:

```
	 ;; create the merge buffer from buffer A, so it inherits buffer A's
	 ;; default directory, etc.
	 (merge-buffer (with-current-buffer
			   buffer-A
			 (get-buffer-create merge-buffer-name))))
```

But I think it doesn't matter if A or B. The problem is that
emerge-diff-buffer has the remote directory and shell command tries to
execute the command on the remote side even through file-A and file-B were
copied to local side in *emerge-files-internal*.


Kind regards, Jörg
