Two same rsync commands give different results on two debian mirrors.

Please see the above line including the part of line-wrapping.  I've used 
the correct rsync tree just as you have noted in the following.

No, I've tried this tree in my above post.  Why do you said I have used a 
wrong rsync direcory tree.  See my above notes for detail.

In fact, the issue I meet is as follows, see the following for detail: 

1- If I append the `/' in the end of the tree, I'll succeed:

werner at debian:~$ rsync -rmnv -f +_README -f -_* ftp.is.co.za::mirror/
ftp.debian.org/ftp.us.debian.org/debian/
[snipped]
receiving file list ... done
drwxr-xr-x          4,096 2015/04/13 11:18:19 .
-rw-rw-r--          1,370 2015/01/10 18:21:28 README

sent 130 bytes  received 886 bytes  96.76 bytes/sec
total size is 1,370  speedup is 1.35 (DRY RUN)

2- If I don't use the `/' in the end of the tree, the rsync will fail to 
retrieve anything:
  
werner at debian:~$ rsync -rmnv -f +_README -f -_* ftp.is.co.za::mirror/
ftp.debian.org/ftp.us.debian.org/debian
[snipped]
receiving file list ... done

sent 23 bytes  received 9 bytes  7.11 bytes/sec
total size is 0  speedup is 0.00 (DRY RUN)

But for the case when use of the following rsync server, both case will 
succeed:

werner at debian:~$ rsync -rmnv -f +_README -f -_* ftp.cn.debian.org::debian 
[snipped]
receiving file list ... done
drwxr-xr-x          4,096 2015/04/14 11:34:19 .
-rw-rw-r--          1,370 2015/01/10 18:21:28 README

sent 47 bytes  received 1,389 bytes  319.11 bytes/sec
total size is 1,370  speedup is 0.95 (DRY RUN)

werner at debian:~$ rsync -rmnv -f +_README -f -_* ftp.cn.debian.org::debian/
[snipped]

receiving file list ... done
drwxr-xr-x          4,096 2015/04/14 11:34:19 .
-rw-rw-r--          1,370 2015/01/10 18:21:28 README

sent 47 bytes  received 1,389 bytes  574.40 bytes/sec
total size is 1,370  speedup is 0.95 (DRY RUN)


Any hints on this issue?
