Subject: "only in" message in recursive diff is ambiguous and hence useless if the directories have the same name

Steps to reproduce:

- have two folders with the same name under different paths such as
/path/to/xxx and /path/to/other/xxx
- Have some files that exist only in one folder, and some that exist
only in the other
- Run:

$ diff -r /path/to/xxx /path/to/other/xxx

You'll get messages like:
  Only in xxx: somefile.txt
  Only in xxx: otherfile.php

You see the problem, right? How stupid is that.
