[Message part 3 (text/plain, inline)]

Hi,

when running `emerge-files` with `/ssh:remote:file` and `~/local-file` I get
the buffer `*emerge-diff-errors*` with:

```
diff: /tmp/tramp.wlcRNL: No such file or directory
diff: /home/joerg/local-file: No such file or directory
```

This change solves the problem:

```diff
diff --git lisp/vc/emerge.el lisp/vc/emerge.el
index ca48f2f3c7b..562041e4232 100644

No response. So I've fixed the diff case. Rcs isn't used widely these

Closing the bug.

Best regards, Michael.
