Your local file system is case insensitive.  
But there are pairs of files in the Internet-drafts directory that differ only in case.
Both files map to the same file on your system.
So each time rsync runs, it finds a file that differs from the local file and overwrites it.  
Next time, it notices that the other file does not match your local file and overwrites it with that.
I laughed out loud when I first noticed this...
