rsync - Dec 2011 - Dir-merge exclude filter ignored when rsync DEST ends in /.

Hi,

I encountered this behavor when switching my excludes
from global exclude filter rules to dir-merge rules.
 
If the spezified DEST directory has a trailing dot dir
the exclude filter rule "exclude /foobar" 
inherited from dir-merge is ignored
and the file gets deleted.

But I'm not quite sure if this behavor is a bug or feature.


Test:

$ mkdir src
$ touch src/object
$ echo "exclude /object" > s/.rsync-filter
bash: s/.rsync-filter: No such file or directory
$ echo "exclude /object" > src/.rsync-filter
$ cp -a src dst
$ ls -flra src dst
src:
insgesamt 4
drwxrwxr-x 2 abcde abcde 39 2011-12-13 16:41 .
drwxrwxr-x 4 abcde abcde 26 2011-12-13 16:41 ..
-rw-rw-r-- 1 abcde abcde  0 2011-12-13 16:41 object
-rw-rw-r-- 1 abcde abcde 16 2011-12-13 16:41 .rsync-filter

dst:
insgesamt 4
drwxrwxr-x 2 abcde abcde 39 2011-12-13 16:41 .
drwxrwxr-x 4 abcde abcde 26 2011-12-13 16:41 ..
-rw-rw-r-- 1 abcde abcde  0 2011-12-13 16:41 object
-rw-rw-r-- 1 abcde abcde 16 2011-12-13 16:41 .rsync-filter

$ rsync -n -avF --delete src/ dst/.
building file list ... done

These DEST directory spezifications works as expected 
(e.g. /object file is ignored):

$ rsync -n -avF --delete src/ dst
building file list ... done

sent 97 bytes  received 20 bytes  234.00 bytes/sec
total size is 16  speedup is 0.14
$ rsync -n -avF --delete src/ dst/
building file list ... done

sent 97 bytes  received 20 bytes  234.00 bytes/sec
total size is 16  speedup is 0.14
$ rsync -n -avF --delete src/ dst/./
building file list ... done

sent 97 bytes  received 20 bytes  234.00 bytes/sec
total size is 16  speedup is 0.14

Tested rsync versions:
rsync  version 2.6.9  protocol version 29
rsync  version 3.0.9  protocol version 30

Kind Regards,
Roland
