This has nothing to do with cygwin. Any new host you ssh to will induce the interchange you saw, and setting the known hosts file to /dev/null will just make it ask every time. It doesn't really know localhost from any other host in this regard. Hope this helps you understand what is happening and that it is perfectly normal AFAIK.
